How DOJ Maintains Prosecutorial Independence—and When That Breaks Down

On January 11, 2026, Federal Reserve Chair Jerome Powell did something federal officials almost never do: he went public about a criminal investigation targeting him. In a video statement, Powell announced that the Department of Justice had served him with a target letter warning him he might be indicted over his congressional testimony about renovation costs at Federal Reserve buildings.

The timing coincided with months of escalating public pressure from President Trump to cut interest rates—pressure Powell had consistently refused.

This raises a question that extends far beyond one investigation: What prevents the Justice Department from becoming a weapon of political control?

How Prosecutorial Independence Is Supposed to Work

The principle is straightforward: individual prosecutors, not the President, decide who gets investigated and charged. This separation exists to prevent the criminal justice system from becoming an instrument of political control.

When Richard Nixon ordered his Attorney General to fire the Special Prosecutor investigating him, Attorney General Elliot Richardson resigned rather than comply. So did Deputy Attorney General William Ruckelshaus. That moment—the Saturday Night Massacre—fundamentally reshaped how Americans understood the relationship between presidential power and prosecutorial independence. The institutional memory of that night has been embedded ever since in formal procedures, informal practices, and structural safeguards designed to create space for prosecutors to make decisions based on law and evidence rather than political considerations.

The DOJ maintains an Office of Professional Responsibility, created after Watergate to investigate whether prosecutors misuse their power. This office theoretically functions as an internal watchdog, empowered to investigate whether prosecutorial decisions have been tainted by improper political considerations.

But these safeguards have a structural problem: they only work if prosecutors follow the rules. The Justice Manual cannot prevent a prosecutor from falsely claiming that a case meets the department’s priorities when political motives drive the decision. The Office of Professional Responsibility cannot investigate misconduct unless someone within the department brings complaints to its attention. Career prosecutors cannot refuse orders from superiors unless the orders violate clear legal standards—which means figuring out whether an investigation is real or fake often requires reading prosecutors’ minds.

That’s why we have other protections: Congress watching the DOJ, courts reviewing cases, and public attention. They’re supposed to catch breakdowns in internal DOJ procedures. The Powell case suggests they might not be working.

When the System Has Broken Down Before

The Saturday Night Massacre set the standard for how we think about this problem. That moment crystallized American legal consciousness around a principle: prosecutors cannot be fired for political reasons.

The immediate aftermath produced structural reforms, including a law creating a special prosecutor independent from the President that existed from 1978 to 1999. The law ended in 1999 amid congressional debates over multiple concerns about the independent counsel statute. While some worried it enabled politically motivated investigations, Congress also grappled with broader questions about prosecutorial independence, accountability, and the proper balance between executive oversight and protection from political interference.

During Trump’s first administration from 2017 to 2021, multiple controversies raised similar questions. Trump publicly called for investigations of Hillary Clinton and former FBI Director James Comey. Prosecutors faced pressure to investigate cases that career prosecutors believed lacked legitimate legal reasons to bring charges. Special counsel Robert Mueller had real protection from the President’s pressure, but Trump’s public criticism and private pressure on the Attorney General created constant tension between executive pressure and prosecutorial independence. The investigation proceeded despite presidential pressure—but only because Mueller had been insulated by the special counsel statute.

Trump returned to office in January 2025. He immediately began pressing the Justice Department to investigate his perceived political enemies. Within weeks, the administration was pushing for investigations and prosecutions of Comey and New York Attorney General Letitia James, both Trump critics.

Federal prosecutors in the Eastern District of Virginia brought charges against Comey in September 2025, based on allegations that he made false statements to Congress years earlier. But then the judge threw out the charges against Comey. The judge’s dismissal was based on findings that the prosecutor’s appointment violated proper procedures. While the dismissal centered on the appointment’s legality, the circumstances—including the replacement of a senior career prosecutor with someone perceived as more aligned with the administration—raised questions about whether the appointment irregularities were designed to enable politically motivated prosecution. A federal judge concluded that the Trump administration had circumvented normal appointment procedures to enable politically motivated prosecution.

How DOJ Safeguards Are Supposed to Function

Investigating someone as important as Jerome Powell normally requires approval from top DOJ officials. Multiple officials normally have to sign off, not one U.S. attorney’s office.

The Justice Manual says prosecutors should ask: Does this fit our priorities? Is there enough evidence? Prosecutors can’t let politics or political goals influence their decisions.

The manual restricts what the White House can say to the DOJ about ongoing investigations. Any White House contact with prosecutors has to go through official channels, be written down, and happen only in specific situations.

If prosecutors get improper pressure from the White House, they have to write it down and tell their bosses. A prosecutor who thinks they’re being ordered to bring charges for political reasons can complain to their superiors.

But these safeguards only work if mid-level and senior DOJ officials are honest. The Deputy Attorney General or Attorney General might decide to prioritize cases for political reasons. In that case, prosecutors’ only real option is to quit.

It’s extremely hard to prove in court that a prosecution is politically motivated. Federal law bans selective prosecution—charging someone because of their race or political beliefs. But to prove selective prosecution, you have to show that other people in the same situation weren’t charged and that the prosecutor’s excuse isn’t the real reason.

Courts have said prosecutors have significant freedom to decide what to investigate and charge. Judges don’t have much power to review prosecutors’ decisions. Someone being investigated can’t go to court before being charged and ask judges to stop the investigation because it appears political.

By the time judges can review the case—after charges are filed—significant damage has already been done. The person’s reputation is destroyed, and they have to spend money and time defending themselves.

Prosecutorial Resignations in Minnesota

Deputy Attorney General Todd Blanche issued a formal statement that there was “currently no basis for a criminal civil rights investigation” into whether an ICE officer’s use of deadly force was justified. This decision marked a sharp departure from past administrations, which have moved quickly to probe shootings of civilians by law enforcement for potential violations of constitutional rights.

Career prosecutors objected to three specific aspects of the DOJ’s approach. First, prosecutors were being pressed to investigate the victim’s family rather than the shooting itself. Second, the Civil Rights Division was being kept out of what would normally be a standard investigation of constitutional rights violations. Third, state authorities were being excluded from the investigation despite initial federal agreements to conduct joint investigations.

NBC News correspondent Ryan Reilly characterized the Civil Rights Division departures as “an entire leadership team walk out the door” representing “a brain drain from which the Justice Department will not be able to recover for a generation.” These were prosecutors with decades of expertise in civil rights investigations.

Legal experts characterized these departures as “reminiscent of the Saturday Night Massacre,” indicating recognition of a fundamental breakdown in institutional mechanisms designed to preserve prosecutorial independence.

The Brennan Center for Justice noted that the Office of Professional Responsibility—established in 1975 to investigate prosecutorial misconduct during the Watergate era—had its head removed by political appointees in the current administration’s first weeks. This removal eliminates an internal watchdog mechanism designed to investigate allegations of prosecutorial abuse.

Is the Powell Investigation Legitimate or Political?

The central question: How do you distinguish legitimate prosecutorial decisions from politically motivated retaliation?

The Justice Department does investigate high-ranking government officials. Prosecutors have legitimate authority to pursue cases involving testimony to Congress. Federal law prohibits knowingly making false statements to Congress.

From a formal standpoint, the DOJ can articulate prosecutorial justification for investigating Powell’s congressional testimony about renovation cost overruns. The question is whether the articulated justification represents the actual prosecutorial reasoning or functions as pretext for a politically motivated investigation.

Several factors suggest the investigation may use a false excuse.

First, Powell provided detailed written documentation of the renovation costs to Congress shortly after his Senate testimony. The letter he sent to key senators in July 2025, following his June testimony before the Senate Banking Committee, provided extensive detail about the renovation project, the history of the buildings, and the factual basis for cost estimates. This formal documentation suggests that he had misspoken and quickly corrected the record through legitimate channels. A prosecutor investigating false statements to Congress must determine not merely whether testimony contained inaccuracies, but whether those inaccuracies were made knowingly and willfully.

Second, the timing. Trump has repeatedly and publicly attacked the Fed Chair for maintaining higher interest rates than Trump prefers. These attacks have included calling him “incompetent” and floating the possibility of firing him. Multiple sources document that Trump has pressured him for months to cut interest rates, and Powell has refused to allow political pressure to influence monetary policy decisions. The investigation emerged after months of this conflict, suggesting that prosecutorial priority may be correlating with political pressure rather than emerging from independent prosecutorial judgment.

Third, Powell explicitly characterized the investigation as political pressure designed to influence monetary policy rather than as a legitimate investigation of factual accuracy. While prosecutors investigating false statements to Congress aren’t supposed to consider the political impact of their investigation, the connection between intense presidential pressure on interest rates and the initiation of an investigation focused on testimony Powell gave becomes relevant evidence in evaluating whether the investigation uses a false excuse.

Has the DOJ previously investigated Federal Reserve chairs for testimony to Congress about renovation costs? The answer appears to be no. Investigating a sitting Federal Reserve chair for criminal conduct appears to be historically without precedent. This lack of historical precedent doesn’t automatically prove selective prosecution, but it does suggest that the investigation represents a departure from normal prosecutorial practice.

When Internal Safeguards Fail: External Checks

Internal DOJ safeguards may prove insufficient to prevent improper prosecutions. In those cases, external checks—congressional oversight, judicial review, and public accountability—theoretically provide additional layers of protection for prosecutorial independence.

Congressional oversight of the Justice Department occurs primarily through appropriations and confirmation authority over the Attorney General and other senior personnel. But Congress lacks real-time authority to halt specific investigations. Senators can threaten to block DOJ nominees or agency funding based on prosecutorial decisions they view as improper. But these remedies operate slowly and aren’t available during pending investigations.

Judicial review of prosecutorial decisions occurs primarily after charges are brought, when defendants can raise selective prosecution and other defenses. The Supreme Court has recognized that the judiciary has limited authority to review prosecutorial decisions made before indictment. Allowing extensive pre-indictment judicial review would paralyze federal prosecutorial operations.

Public accountability mattered in Powell’s case because he decided to tell the public about the investigation in a video. This is almost never done. Normally, criminal investigations are kept secret. He publicly said the DOJ was threatening to indict him, breaking protocol but creating public scrutiny. Even Republicans appointed by Trump criticized the investigation as unfair and unprecedented. This public debate created accountability that wouldn’t exist if the investigation had stayed secret.

But this only works if the person being investigated is famous, trusted, and has media access. Ordinary people without media access or fame have no way to create this kind of accountability. Ordinary people get much less protection from political prosecution than famous officials do.

Legitimate Policy Priorities vs. Political Persecution

Federal prosecutors can’t investigate every possible federal crime. Federal laws cover a huge range of behavior, and violations happen everywhere. Prosecutors have to decide which cases matter most, which to investigate, and which to ignore.

Presidents can legitimately influence these choices through the Attorney General, who can tell prosecutors which crimes to focus on. A president can legitimately tell the DOJ to focus on national security, violent crime, environmental violations, or other priorities.

It’s hard to tell the difference between legitimate policy guidance and improper political pressure. President Trump told the DOJ to focus on immigration enforcement. Prosecutors could say they were following the policy when they charged undocumented immigrants. Yet the same administration seems to have used immigration charges against people who criticized its immigration policies.

The renovation costs might have been fraudulent. Powell might have lied to Congress to hide that the Federal Reserve wasted taxpayer money. In that case, investigating him would be legitimate. But the investigation might be based on normal disagreement about spending, or on political pressure from the White House. In that case, prosecutors have broken the rules. His letter to senators explained the renovation costs, suggesting he corrected any mistakes through normal channels. Yet prosecutors could argue that fixing it later doesn’t excuse lying in the first place. The fact that prosecutors can argue either way shows the real problem: you can’t tell if a prosecution is legitimate or political by looking at the facts.

Prosecutorial Independence in Other Democracies

Other democracies have faced the same tension between executive power and prosecutorial independence. Germany’s constitutional court says prosecutorial independence is a constitutional right. German prosecutors work in a system with written laws that protect them from executive pressure. Canada has made prosecutorial independence a constitutional right and built it into its laws and court rules.

By contrast, democracies that let prosecutors become political tools have seen the rule of law collapse. Argentina, Indonesia, Turkey, and others let politicians control prosecutors, which led to political prosecutions and loss of public trust. These examples show that prosecutorial independence doesn’t happen automatically—you have to protect it. Without strong protections and a culture that respects prosecutorial independence, leaders can easily turn criminal law into a political weapon.

After Watergate, the United States committed to protecting prosecutorial independence. Americans came to understand that letting the executive control prosecutors would destroy the rule of law. These commitments have been challenged repeatedly in recent years. The Powell investigation is perhaps the clearest test: Will prosecutorial independence survive when a president directly pressures the DOJ to investigate officials who disagree with him?

What Comes Next

The current controversy surrounding the Fed Chair, the ICE shooting investigation resignations, and the investigations of Comey and James suggest that prosecutorial independence as a governing principle is under unprecedented pressure.

Powell might be indicted despite widespread concerns that the investigation is political. That would be unprecedented and would show that current protections can’t stop political prosecutions of top officials.

Political pressure or courts might stop the investigation based on selective prosecution arguments. That would show that outside accountability can work even when the DOJ’s internal rules fail.

How his case turns out will likely affect how other people being politically targeted respond. It might determine whether prosecutorial independence actually limits presidential power or becomes something we wish for.

Procedural reforms alone can’t solve this tension. It ultimately depends on DOJ officials choosing legitimate legal reasons over politics. It depends on Congress using its power to confirm judges and control funding to protect prosecutorial independence. And it depends on the public understanding and supporting the idea that prosecutors need to be independent from the president.

If the president can use criminal law to punish disagreement or pressure officials, that destroys the rule of law and democracy. Whether American prosecutorial independence can survive this is the constitutional question the Powell investigation raises.
