What Trump’s Security Clearance Defeats Mean for Presidential Power

On December 23, 2025, a federal judge blocked President Trump’s attempt to revoke the security clearance of Mark Zaid, a national security attorney who has spent his career representing government whistleblowers.

Throughout 2025, the Trump administration systematically targeted critics, whistleblower attorneys, and entire law firms by revoking security clearances and blocking government contracts. Judges blocked these efforts repeatedly, finding they violated the First Amendment and basic due process.

The question at the heart of these cases is whether any president can weaponize government powers to silence opposition, punish protected speech, and destroy the careers of people who represent clients the administration dislikes. The answer, according to multiple federal judges, is no.

What Security Clearances Are

A security clearance is permission to access classified information. The system has three levels: Confidential (lowest), Secret (middle), and Top Secret (highest).

The “need to know” principle matters here. Having Top Secret clearance doesn’t mean you can browse whatever classified files interest you. You need both the clearance level and a legitimate work-related reason to access specific information.

About 4.1 million Americans hold active clearances, mostly federal employees and defense contractors. Getting a Top Secret clearance takes 6 to 18 months and costs the government roughly $5,596 per person for background investigations.

Some former high-ranking officials keep their clearances after leaving government. They need a sponsor—usually their old agency—and they need an ongoing relationship that justifies maintaining the clearance. The stated purpose is to benefit the government, not the individual.

This arrangement has worked for decades with minimal controversy because former officials rarely used their clearances unless specifically contacted by current officials.

Mark Zaid’s situation is different. He’s a practicing attorney who represents clients in national security matters, including government whistleblowers and employees facing clearance denials. His work requires accessing classified information during legal proceedings. Without his clearance, he cannot represent clients in national security cases.

The 2018 Brennan Case

In August 2018, President Trump revoked former CIA Director John Brennan’s security clearance, citing his “erratic conduct and behavior.” No modern president had weaponized clearance revocation as political punishment before.

Press Secretary Sarah Huckabee Sanders declared the revocation publicly, but 13 days later, Brennan still hadn’t received formal notification from any government agency. Trump had declared it by press release without going through official channels.

This gap between announcement and implementation revealed something about how executive power works: even in areas where presidents have constitutional authority, implementation involves multiple agencies, procedures, and documentation.

The Brennan case raised questions about what a security clearance is for. According to law and presidential directives, clearances exist to serve government interests, not personal interests. If a former official uses their clearance primarily for personal benefit—paid television commentary, book deals, speaking fees—that undercuts the stated rationale.

Brennan had a contract with NBC News and frequently appeared on television criticizing Trump. Some experts argued he was monetizing his clearance in ways previous intelligence officials hadn’t. Others countered that former officials shouldn’t be silenced from public commentary simply because they retain clearances.

A former CIA director can write op-eds without divulging classified information. The clearance doesn’t cause the speech—it’s background that establishes credibility.

2025: From Individual Targets to Systematic Campaigns

On January 20, 2025, Trump issued an executive order directing revocation of security clearances for 51 former intelligence officials who had signed a 2020 letter suggesting that Hunter Biden’s laptop had “all the classic earmarks of a Russian information operation.”

The administration’s position: these officials had “willfully weaponized the gravitas of the Intelligence Community to manipulate the political process” before the 2020 election. The order also targeted former National Security Advisor John Bolton for publishing a memoir containing sensitive information.

In March 2025, Trump issued another memorandum targeting 15 additional individuals, including Mark Zaid and multiple other critics. The targets spanned political and legal spheres: former Deputy Attorney General Lisa Monaco, New York Attorney General Letitia James, members of Biden’s family.

The March memorandum simply asserted it was “no longer in the national interest” for these individuals to access classified information. No detailed justification for each person. No investigation. No explanation.

What the Judge Found

Judge Amir Ali’s December 23 ruling in the Zaid case identified multiple constitutional problems. The core finding was straightforward: the revocation was motivated by retaliation for Zaid’s representation of whistleblowers and clients opposed to the government.

The revocation was “arbitrary and process-devoid,” meaning it was made without applying any consistent standard or procedure and without affording Zaid basic safeguards.

The administration didn’t investigate whether Zaid had mishandled classified information. Didn’t determine he was a security risk. Didn’t provide him any opportunity to respond before revoking his clearance.

The judge found that the government violated Zaid’s First Amendment rights by using clearance revocation power to punish him for protected speech and legal advocacy on behalf of clients the administration opposed. A law firm can’t have its clearances suspended because the government dislikes the clients it represents. A lawyer can’t lose her clearance because she represents government critics.

The government can revoke privileges based on legitimate security concerns. But it cannot use those revocation powers to suppress speech and legal advocacy.

Zaid has a protected liberty interest in pursuing his profession as a national security attorney—and clearances are essential to that work. Before the government can deprive someone of a constitutionally protected interest, it must provide due process: notice of the charges, an opportunity to be heard, and a decision-maker who fairly considers the evidence.

The Trump administration did none of this. It simply issued a memorandum stripping 15 people’s clearances without investigation, explanation, or opportunity to respond.

The Government’s Defense

The government argued that security clearances are purely an executive matter and that courts have no role reviewing presidential decisions about national security. This invokes the “political question doctrine“—the idea that some decisions are so fundamentally about politics and national security that courts should stay out.

Judge Ali rejected this argument as too broad. While courts should defer to the executive on predictive national security judgments—whether a particular country poses a threat, whether certain technology endangers national security—courts can and should review whether the procedures used respect constitutional requirements.

A president might legitimately believe someone is a security risk and should lose clearances. Courts would hesitate to second-guess that judgment. But a president cannot declare a political opponent a security risk without any investigation or evidence and then hide behind national security claims when courts ask what happened.

Courts can ask: Did you follow fair procedures? Did you provide the person accused a chance to respond? Is this decision based on viewpoint discrimination rather than legitimate security concerns?

The Law Firm Cases

Jenner & Block, Paul Weiss, Perkins Coie, WilmerHale, and Susman Godfrey all sued after Trump issued executive orders suspending their employees’ security clearances and restricting federal contracts with their firms. In case after case, federal judges blocked these orders, finding they violated the First Amendment, the Fifth Amendment right to counsel, and basic procedural due process.

Judge Beryl Howell found that Executive Order 14230 targeting Perkins Coie was “an unprecedented attack” on the legal system, violating the Constitution by preventing Americans from selecting counsel of their choice without fear of government retaliation.

Judge John Bates, a George W. Bush appointee, ruled that the executive order against Jenner & Block sought to “chill legal representation the administration doesn’t like.”

Judge Loren AliKhan, considering Susman Godfrey’s case, said the order violated “the vision of the Founding Fathers” and was “a shocking abuse of power.”

The administration’s argument was: we don’t like certain lawyers and law firms, we consider their legal work contrary to the national interest, and therefore we want to revoke their security clearances and prevent their firms from getting government contracts.

The courts said: that’s exactly the kind of viewpoint discrimination and political retaliation the Constitution forbids.

How This Changes the Legal Framework

Courts will defer on predictive national security judgments. But courts will scrutinize whether the government is using national security powers for unconstitutional purposes. You can’t hide behind national security claims while engaged in viewpoint discrimination.

In United States v. Nixon, the Supreme Court held that while executive privilege is real and important, it is not absolute and can be overcome in certain circumstances. The Court wrote that courts are capable of reviewing assertions of executive privilege and determining when it applies and when it doesn’t.

That principle—that executive claims can be reviewed—extends beyond traditional executive privilege to other areas of executive authority.

In National Rifle Association v. Vullo, cited in the Zaid case briefs, the Supreme Court held that the government cannot indirectly punish protected speech by threatening government benefits or privileges, even if those benefits are normally within executive discretion.

If a state official threatened to revoke a corporation’s license because the corporation funded pro-gun organizations, that would be unconstitutional coercion of speech, even though the state normally has power over licensing. The same principle applies to security clearances: even though presidents have power over clearances, they cannot use that power to punish protected speech.

Who Got Hit and Why It Reveals the Pattern

The January 2025 executive order targeting 51 intelligence officials focused on those who signed the October 2020 letter about Hunter Biden’s laptop. That letter, released just before the 2020 election, stated that the laptop story had “all the classic earmarks of a Russian information operation,” suggesting it was disinformation rather than authentic material.

Signatories included former CIA Directors John Brennan and Michael Hayden, former Defense Secretary Leon Panetta, and numerous other intelligence officials.

The letter said the story had “all the classic earmarks” of Russian disinformation—it was a judgment call about information operations, not a statement of absolute fact. The Trump administration believed these officials had gotten the assessment wrong and had used their classified information credentials to mislead the public before an election.

What the courts examined was whether the Trump administration could revoke clearances because officials expressed views the president disagreed with.

The March 2025 memorandum targeting Mark Zaid and 14 others followed a different logic. It targeted people who had represented or supported people the Trump administration viewed as adversaries: lawyers who worked on January 6 cases, attorneys general who opposed Trump policies, and others.

Mark Zaid’s inclusion was telling. His work included representing the intelligence community whistleblower whose account of a Trump phone call with Ukrainian President Volodymyr Zelenskyy helped trigger the first Trump impeachment. In 2025, he filed a lawsuit on behalf of FBI employees alleging they were being targeted because of their work investigating the January 6 Capitol riot.

The pattern that emerged was less about legitimate national security concerns and more about using government power to punish political opponents, critics, and those who had worked against the administration.

If the Trump administration were concerned about national security risks, courts asked, why were the targets overwhelmingly people who had opposed the administration? Why were there no security investigations, no evidence presented, no opportunity for the targets to respond?

What This Means for Presidential Power Going Forward

Presidents cannot use national security powers as cover for political retaliation. If a president wants to deny someone access to classified information because that person is an actual security risk—because they’ve mishandled secrets, have demonstrated unreliability, or have become vulnerable to foreign influence—courts will defer to that judgment.

But if a president wants to punish someone for speech, legal advocacy, or political opposition and tries to disguise it as a security decision, courts will look behind the curtain.

Even national security matters require basic procedural fairness. The Constitution’s due process requirement doesn’t disappear because national security is involved. The government must provide notice, an explanation of the reasons for its action, and an opportunity for the affected person to respond.

These procedures can be adapted for classified information—you don’t have to give someone access to sources and methods—but they can’t be eliminated.

The First Amendment prevents government from conditioning government benefits on citizens’ silence about controversial topics. You can’t lose your security clearance because you speak out about government policies. You can’t lose your clearance because you represent clients the government opposes. You can’t lose your clearance because you criticized the president.

The government can refuse to grant clearances or revoke them for legitimate reasons, but viewpoint is not one of them.

This applies to all future administrations, not Trump. These are constitutional principles, not anti-Trump rulings. A Democratic president in the future would be equally bound by them. Presidents cannot use their control over clearances to punish people who oppose them, regardless of which president is doing the punishing.

These constraints represent a reduction in unilateral executive power, though not an elimination of it. Presidents still control access to classified information. Presidents can still revoke clearances. But they must follow procedures and cannot act arbitrarily or as pure political punishment.

The Appeals Process

The Trump administration has signaled its intent to appeal Judge Ali’s preliminary injunction ruling to the U.S. Court of Appeals for the D.C. Circuit.

The preliminary injunction is temporary—it stops the government from implementing the revocation while the case continues. The appeal will be decided by a three-judge panel of the circuit court, and the government will argue that the judge was wrong to block the revocation.

The circuit court will apply an abuse-of-discretion standard, asking whether the district judge misapplied the law or acted unreasonably in granting the preliminary injunction. The government might argue that security clearances are such a core presidential function that courts cannot review them. Or they might argue that even if courts can review clearance decisions, the judge applied the wrong legal test or failed to properly weigh national security concerns against First Amendment interests.

After the circuit court rules, the losing side could ask the Supreme Court to review the case. Supreme Court review is not automatic—the Court receives thousands of petitions annually and accepts only about 70 cases. For the Court to take the case, four justices must believe it involves an important constitutional question that deserves the Court’s attention.

If the Supreme Court does take the case, it would probably issue a decision by June 2026 at the earliest. The Court’s current composition, with a conservative majority, might or might not be inclined to expand executive power. While conservative justices have sometimes favored robust executive authority on national security matters, some have also expressed concern about executive overreach and retaliation against protected speech.

Meanwhile, the other law firm cases are also on appeal. As of late 2025, multiple appellate courts were considering whether the executive orders targeting Perkins Coie, Jenner & Block, and others violated the Constitution. If these appeals are also lost by the government, the pattern of judicial constraint on this form of executive power becomes stronger.

What This Means for Different Groups

For career federal employees with security clearances: This ruling strengthens protections against political retaliation. If an agency tries to revoke your clearance because you reported wrongdoing, exercised your right to speak to Congress about agency problems, or opposed agency policies, you now have stronger grounds to challenge that action in court.

For national security lawyers and their clients: The decision protects the ability to seek counsel and provide counsel in national security matters without fear that exercising First Amendment rights will result in retaliation. A whistleblower can talk to a lawyer about reporting government wrongdoing without worrying that the lawyer will lose her clearance as punishment.

A defendant in a national security case can retain counsel known for defending national security matters without that attorney being targeted for retaliation.

For the intelligence community and national security establishment: These decisions impose new procedural requirements and make it harder to revoke clearances for political reasons. Career intelligence officials will need to be confident that their clearances won’t be revoked because they express policy disagreements with whoever is in the White House.

This supports the longstanding principle that the intelligence community should be independent from partisan politics.

For the public and the constitutional system: These decisions affirm that the Constitution applies even to national security matters. Presidential power is not unlimited. Even in areas like national security where courts have traditionally deferred to the executive, there are constitutional boundaries that courts will enforce.

For future administrations: Democratic and Republican administrations alike will now know that courts can and will review clearance revocations, particularly when they appear motivated by political retaliation rather than genuine security concerns. This should discourage future administrations from attempting similar campaigns.

The Intelligence Community’s Perspective

Former intelligence officials and current agency leaders have mostly welcomed these court decisions. The intelligence community has long valued its distance from partisan politics. Career intelligence professionals see themselves as serving the nation, not parties or presidents.

When a president attempts to weaponize intelligence agency powers for political purposes, it undermines this professional ethic.

The principle that intelligence agencies should be independent from partisan politics is itself an important constitutional value. Intelligence can become dangerously politicized if intelligence leaders fear that supporting the wrong analysis or opposing the president’s preferred policies will result in retaliation.

The clearance revocation campaign, from the intelligence community’s perspective, represented this kind of politicization risk.

Former CIA leadership has emphasized that intelligence analyses should be based on evidence and professional judgment, not political loyalty. When former intelligence officials lose clearances because they disagreed with the president’s positions or expressed criticism, it sends a message to current officials that similar consequences might befall them for speaking truth to power.

Intelligence leaders from both parties have historically worried about excessive politicization of intelligence. Republican and Democratic officials alike have argued that intelligence must maintain professional independence.

Can Presidential Power Be Truly Limited?

The significance of the Zaid ruling depends on how robustly courts enforce these principles going forward. If this was a one-off case where a particular judge happened to rule against executive power, the practical impact might be limited.

But if it represents a shift—courts willing to second-guess presidential national security decisions when constitutional rights are at stake—the implications are profound.

The history of presidential power in America is largely a history of presidential power expanding. Chief Justice John Marshall wrote that the president is the “sole organ” of foreign policy, suggesting minimal judicial role. The Cold War expanded executive authority dramatically. National security became a catch-all justification for executive action.

For decades, the political question doctrine took most national security matters off-limits from judicial review.

But recent Supreme Court decisions suggest limits to this expansion. In Hamdi v. Rumsfeld, the Supreme Court held that even in fighting terrorism, the government must follow certain procedures and cannot act completely unilaterally. In cases addressing executive privilege and subpoena power, the Court has held that executive claims can be reviewed.

The courts of appeals that have ruled on the law firm cases have consistently found constitutional violations despite government invocations of national security.

What appears to be happening is a recalibration rather than a reversal. Courts are not saying presidents have no discretion over national security or that every national security decision can be litigated. Rather, courts are saying that national security power is subject to constitutional limits, particularly when First Amendment rights and individual liberty are at stake.

When a president appears to be using national security power not for national security purposes but for political punishment, courts will intervene.

The Historical Precedent Problem

One reason the Trump administration’s clearance revocation campaign encountered legal trouble is that it was doing something unprecedented. Presidents had never before attempted to systematically revoke the clearances of critics and political opponents as a form of retaliation.

John Brennan’s 2018 clearance revocation was controversial partly because it was novel. But even that paled in comparison to the 2025 campaign targeting 51 intelligence officials, then 15 more individuals, and then entire law firms.

This lack of precedent matters for legal analysis. When something has never been done before, courts are more likely to scrutinize it. If presidents had a long history of using clearance revocation for political purposes without opposition, courts might be more inclined to accept it as normal presidential prerogative.

Instead, the Trump administration was establishing a new practice, and courts decided that practice violates the Constitution.

Historical practice is a source of constitutional meaning. The Constitution doesn’t explicitly say the president cannot use national security powers for political punishment. But the longstanding practice of respecting independence in national security matters, not weaponizing clearances, and following procedures before revocation all became part of the constitutional understanding.

The Trump administration’s attempt to depart from this practice triggered constitutional objections.

Potential Legislative Responses

The Zaid decision and related rulings might prompt Congress to codify security clearance procedures into statute, removing some presidential discretion. Congress could pass legislation requiring detailed investigations before clearances are revoked, mandating procedural safeguards like notice and opportunity to be heard, and explicitly prohibiting clearance revocation as punishment for speech or legal advocacy.

Some proposed legislation already exists. The Senate has considered bills to protect whistleblowers from security clearance retaliation. There are proposals to create statutory procedures for clearance revocation that would replace reliance on executive orders.

Such legislation would reduce presidential flexibility but would also reduce presidential discretion to abuse the clearance system.

Alternatively, Congress might strengthen whistleblower protections specifically within the national security context, making it clear that employees who report wrongdoing cannot have their clearances revoked in retaliation. Existing laws like the Whistleblower Protection Act provide some protection, but adding specific language about clearances would reinforce it.

The intelligence community itself might impose new standards. The Office of the Director of National Intelligence (ODNI) could issue new guidance requiring security-based justifications for clearance revocations and prohibiting political motivations. Agencies could establish internal appeal processes that are more robust than current procedures.

None of these changes would eliminate presidential authority over clearances. They would channel that authority through procedures designed to ensure it is not abused.

The Meta-Question About Checks and Balances

The Zaid case is one piece of a larger puzzle about presidential power and accountability in the modern era. Throughout 2025, federal judges blocked numerous Trump administration actions, from law firm executive orders to immigration policies to foreign aid freezes. In case after case, courts found that executive orders violated the Constitution or exceeded presidential authority.

As one legal ethics professor told Law.com, the Trump administration appeals of these lost cases serve purposes beyond winning on the merits. By appealing, the administration keeps cases alive, forces law firms and organizations to incur legal costs and live with uncertainty, and sends a message to others who might challenge the administration that resistance will be costly.

Even losing appeals can have a chilling effect.

The Zaid ruling addresses part of this problem by issuing a preliminary injunction—stopping the government from implementing the revocation while the case proceeds. This prevents the administration from imposing the harm while litigation continues.

Preliminary injunctions are what make constitutional protections meaningful rather than merely theoretical.

Limits of the Victory

While the Zaid decision and related rulings represent limits on presidential power, they are not absolute victories for those challenging executive authority.

First, these are preliminary rulings and circuit court decisions. They are not final Supreme Court determinations. The Supreme Court could ultimately reverse them, though that seems unlikely given the breadth of constitutional concerns identified.

Second, judges still defer to presidential judgments about national security on the merits. If the Trump administration or any administration wants to revoke someone’s clearance and can articulate a plausible security-based reason for doing so, courts will likely accept that judgment. The rulings prevent pretextual revocations motivated by viewpoint discrimination, but they don’t require courts to second-guess real security determinations.

Third, these rulings apply narrowly to situations where First Amendment rights and protected advocacy are involved. They don’t protect employees from clearance revocation for legitimate security reasons—mishandling classified information, dishonesty, foreign influence, or unreliability.

Fourth, the rulings protect against retaliation for specific protected activities like legal advocacy, speech about government policies, and whistleblowing. They don’t protect everyone from all clearance denials or revocations. Someone denied a clearance for a criminal conviction or financial irresponsibility wouldn’t be protected by these rulings.

Fifth, the practical implementation of these court decisions depends on the executive branch’s compliance. If the Trump administration simply ignored the injunction and continued implementing revocations, the court would need to enforce its order through contempt proceedings.

Courts depend on executive compliance. If an administration deliberately flouts court orders, that creates a more fundamental constitutional crisis about separation of powers.

What Comes Next

The Zaid ruling establishes an important principle: presidential authority over national security matters is not absolute. Courts will review executive actions to ensure they comply with the Constitution, particularly when First Amendment rights and procedural due process are at stake.

Presidents cannot use national security powers as cover for political retaliation against critics, whistleblowers, and those who exercise protected rights.

This represents a constraint on executive power compared to the previous era when courts almost never reviewed national security decisions. It does not eliminate presidential discretion or return to a world where the president is powerless in national security matters.

Rather, it establishes constitutional guardrails: you can have discretion, but you must use it fairly, with procedures, and for legitimate purposes rather than political punishment.

For Americans watching debates about presidential power grow more intense, the Zaid case offers a reminder that constitutional limits still matter. A president cannot do anything in the name of national security. Courts will intervene when constitutional rights are at stake.

Those limits work imperfectly and slowly, through the courts, but they work.

The appeals process will continue for months or years. Ultimately, the Supreme Court might weigh in. But for now, Mark Zaid keeps his clearance, law firms keep their employees’ clearances, and a principle is established: even in national security matters, the Constitution applies.
