What Congress Can Do If DOJ Investigations Threaten Fed Independence

In January 2026, the Department of Justice opened a criminal investigation into Federal Reserve Chair Jerome Powell for statements he made to the Senate Banking Committee about a building renovation. Powell’s response was immediate and unambiguous: this wasn’t about construction costs or Congressional testimony. This was about whether the President could use criminal prosecution to pressure the Fed into lowering interest rates.

The investigation exposes something Congress never anticipated when it designed the Federal Reserve’s independence more than a century ago. What happens when a President can’t fire the Fed chair for policy disagreements, so he investigates him for a crime instead?

Congress now faces a question with no clear answer in existing law. The Federal Reserve Act protects Board members from removal except “for cause”—meaning the President can’t fire Powell because he disagrees with interest rate decisions. But the Justice Department can open a criminal investigation into Powell’s Congressional testimony, creating the pressure that removal protections were designed to prevent.

Powell’s term as chair expires in May 2026. His potential successor, Kevin Warsh, awaits Senate confirmation. Congressional leaders are trying to figure out, in real time, what authority they have to defend an institution they created from an executive branch that’s found a workaround to the rules.

What Congress Built

The Federal Reserve’s independence wasn’t an oversight or a tradition that evolved informally. Congress chose it deliberately.

Congress, not the President, sets the Fed’s statutory mandate: price stability and maximum employment. Congress confirms Fed appointees through the Senate. Congress appropriates funds for Fed operations and requires regular testimony from Fed chairs. Congress can reform or restructure the Fed through legislation.

Congress learned through painful experience that when central banks become subservient to short-term political pressures, the results are inflation, economic instability, and erosion of public trust.

But Congress apparently didn’t anticipate a President who can’t fire the Fed chair might investigate him instead.

The Investigation and Its Context

The stated reason for the DOJ investigation is that Powell may have made false or misleading statements to the Senate Banking Committee about the scope and costs of the Fed’s headquarters renovation project.

President Trump has spent months publicly pressuring Powell to lower interest rates, threatened to remove him, proposed legal action tied to the renovation, and demanded sharply lower rates. The investigation was announced months after Powell resisted these demands.

If a President can accomplish through criminal prosecution what he cannot accomplish through removal—pressuring the Fed to change policy or creating reputational damage that undermines the institution’s credibility—then the statutory removal standard becomes meaningless. When a Fed chair knows that testimony to Congress about spending practices could trigger prosecution, the chilling effect on honest Congressional communication becomes real.

Congress’s Existing Tools

Congress has substantial authority over the Justice Department. The question is which tools it can appropriately deploy without crossing constitutional lines.

Congress appropriates all funds for DOJ operations and has historically used special conditions attached to spending bills to restrict how executive agencies can use those funds. Language could theoretically prevent DOJ from using appropriated funds to investigate federal officials for testimony given to Congress about agency spending practices. The constitutional validity of such a condition is uncertain—Congress has authority over the purse, but the idea that different branches of government should have separate powers may prevent Congress from using appropriations to control individual prosecutorial decisions.

Congress’s confirmation power offers clearer ground. Senator Thom Tillis has announced he will block any Federal Reserve nominee until the investigation into Powell is resolved. The Senate must affirmatively consent to Fed appointments, and Senators can exercise that power based on their assessment of whether nominees will protect institutional independence.

Congress also has investigatory and oversight authority, which are constitutionally protected and can create political pressure that affects executive decisions.

Congress cannot directly control individual prosecutorial decisions. Congress cannot pass legislation saying “the DOJ must not investigate Federal Reserve Chair Jerome Powell.” That would constitute direct Congressional control of a specific prosecutorial decision—a violation of the separation of powers. The executive branch has the authority, and bears the responsibility, for prosecuting violations of federal law.

Congress’s challenge is developing tools that protect Federal Reserve independence through lawful means without crossing into unconstitutional control of prosecutorial decisions. A narrow path exists.

Republican Defections and Legislative Opportunity

Congress’s response has divided largely along party lines, but with notable Republican defections that matter.

Tillis’s position is particularly significant. Republicans hold a 13-11 majority on the Senate Banking Committee. If every Democrat and Tillis oppose a Fed nominee, that nominee cannot advance from committee.

This suggests potential bipartisan space for Congressional action to protect Fed independence. Beneath the immediate tactical question of blocking Federal Reserve nominations lies a strategic opportunity: Congress could use this crisis to enact permanent statutory protections that prevent future administrations from deploying prosecutorial power to pressure the Fed.

A Federal Reserve Independence Act: Key Elements

A Federal Reserve Independence Act could include several key elements, each designed to address different aspects of the threat while respecting constitutional constraints.

Explicit statutory protection for Congressional testimony: Congress could enact language stating that no federal official working for or serving on the Federal Reserve Board can be investigated or prosecuted for statements made in testimony to Congress regarding agency operations, spending, or policies, unless prosecutors can demonstrate strong proof that someone deliberately lied about important facts. This would establish a tougher legal test prosecutors would need to meet.

Procedural requirements before investigating Fed officials: Before DOJ initiates an investigation of a Federal Reserve Board member or Chair, the Attorney General must provide written notice to the Congressional Banking Committees explaining the specific factual predicate for the investigation, the alleged conduct, and the justification for why the investigation is warranted. This would create transparency and allow Congress to exercise oversight authority.

Strengthened “for cause” removal standard: Congress could amend the statute to provide greater specificity about what constitutes cause and to establish procedural protections for Board members facing removal. Congress could specify that policy disagreements do not constitute cause, that removal decisions are subject to judicial review, and that Board members have the right to a hearing before removal.

Enhanced independence protections for internal decision-making: Congress could strengthen statutory language preventing anyone from threatening, pressuring, or intimidating Federal Reserve officials regarding their policy decisions. Such language would need careful drafting to avoid preventing legitimate Presidential communication with the Fed, but it could establish clear statutory prohibitions against using investigations, termination threats, or other coercive means to influence monetary policy decisions.

International Models for Central Bank Independence

These statutory protections would build on international models that have developed legal frameworks for central bank independence. The Bank of England Act of 1998 established detailed legal protections for the Bank’s ability to make day-to-day decisions without political interference, including explicit provisions about the Bank’s relationship with the government and limits on government authority over monetary policy.

The European Central Bank’s independence is protected through multiple treaties establishing that the ECB “shall not seek or take instruction from any institution, government or other body” and that member governments “must respect this principle and not seek to influence the members of the decision-making bodies of the ECB.”

Germany’s Bundesbank Act codifies that the central bank is “independent of and not subject to instructions from the Federal Government.” The law specifies mechanisms supporting this independence: separate financial arrangements, sufficiently long terms of office for decision-makers, no reappointment of Executive Board members, prohibition of the central bank directly lending money to the government, and the ability to make decisions without outside pressure.

The international models share common elements: independence is codified in statute or treaty rather than merely asserted. Specific mechanisms protect the personal independence of decision-makers through term lengths and removal protections. Financial and organizational independence is specified. There are clear legal boundaries between what government can direct and what the central bank independently decides.

When the UK Parliament granted the Bank of England the ability to make day-to-day decisions without political interference in 1998, it created specific legal mechanisms supporting it. The act establishes the Bank’s governance structure, specifies decision-making procedures, and creates reporting obligations that ensure the Bank remains accountable while maintaining independence from political pressure. The statute places the Bank’s policy decisions outside the domain of government direction.

The ECB framework addresses the personal independence of decision-makers. Executive Board members serve non-renewable eight-year terms and can be removed from office “only in case of serious misconduct” as determined by the European Court of Justice. This combination of limited, non-renewable terms with strong removal protections and independent judicial review reflects sophisticated understanding that central bank independence depends on protecting individuals who make policy decisions from political retaliation.

Germany’s approach is particularly instructive because Germany has deep historical experience with central bank subordination to political pressure and the disastrous consequences that follow. The Bundesbank Act addresses how independence functions when the central bank carries out tasks in cooperation with other government authorities. The Bundesbank conducts some supervisory functions alongside the government’s banking regulator, and the law clarifies that independence in monetary policy does not preclude cooperation with government in supervision. Congress could adopt language similar to the German model, protecting monetary policy independence while acknowledging legitimate government involvement in financial supervision.

Constitutional Constraints on Congressional Action

Congress must work within constitutional constraints. The idea that different branches of government should have separate powers prevents Congress from exercising executive power or from taking away the President’s power so thoroughly that the President cannot execute the laws.

The Constitution vests executive power in the President, including the power to decide which cases to prosecute. This prevents Congress from passing legislation that says “the DOJ must not investigate Federal Reserve Chair Jerome Powell.”

However, Congress’s power is broader when it addresses general conditions, procedures, or categories of conduct rather than specific prosecutorial decisions. Congress can pass special conditions attached to spending bills placing conditions on how DOJ uses federal funds. Congress can establish statutory requirements for transparency and requiring the administration to tell Congress before taking action when investigating certain categories of officials. Congress can use its confirmation power as leverage to create political incentives for executive action.

Congress cannot pass legislation saying “the DOJ must dismiss the Powell investigation.” Congress can pass legislation establishing that no federal funds may be used to investigate Federal Reserve officials for testimony about agency operations, requiring notice to Congress before such investigations begin, or establishing procedural requirements that must be followed. Congress can hold oversight hearings and use confirmation power as leverage. Careful drafting can achieve substantial protective effects while respecting constitutional constraints.

Congressional Precedent for Protecting Officials from Political Pressure

The independent counsel statute, enacted in 1978 in response to the “Saturday Night Massacre” during Watergate, represents the most direct precedent. When President Nixon’s pressure led to the firing of Special Prosecutor Archibald Cox, Congress responded by creating an independent counsel mechanism for investigating alleged wrongdoing by executive officials. The statute established that an independent counsel appointed by a court could investigate executive branch officials and could be removed only “for cause”—the same removal standard now applied to Federal Reserve Board members. While the independent counsel statute expired in 1992, it demonstrated Congressional willingness to create statutory protections against executive pressure on investigative authority.

More recent precedent involves Congressional protection of inspectors general. In 2008, Congress amended the Inspector General Act to require that the President provide Congress 30 days’ notice before removing an inspector general and that the President provide detailed reasons specific to each situation. After the Trump administration removed five inspectors general in 2020, Congress in 2022 further amended the Act to require that the President provide detailed reasons specific to each situation for removal.

These precedents suggest Congress could enact Federal Reserve independence protections without attempting to control the power to decide which cases to prosecute directly. Congress could require notice to the Banking Committees before investigating Federal Reserve officials, could demand that DOJ provide detailed written justification for opening investigations, could establish procedural requirements that must be followed, and could use these mechanisms to create political pressure and transparency.

Immediate Leverage: Confirmation as a Tool

While longer-term legislative solutions merit consideration, Congress faces an immediate decision regarding Federal Reserve personnel. Powell’s term as Chair expires in May 2026, and President Trump has nominated Kevin Warsh as Powell’s successor.

Tillis has made clear he will not advance any Federal Reserve nominee—including Warsh—until the Powell investigation is resolved. His position provides leverage because with all Democrats opposed, Tillis alone can block a nominee from advancing out of committee.

The Senate Banking Committee can signal that nominees will not move forward until the Powell investigation is either completed and resolved or is withdrawn by DOJ. This approach uses Congressional authority constitutionally—the Senate has the power to confirm or reject nominees, and Senators can exercise that power based on their assessment of whether nominees will protect institutional independence.

Warsh’s confirmation may depend on whether DOJ withdraws or completes the Powell investigation. If the investigation produces an indictment, Tillis is likely to continue his opposition. If prosecutors find insufficient evidence to pursue charges, the investigation’s closure might allow movement on nominations. If the investigation persists indefinitely without resolution, the confirmation logjam could persist through 2026 and into 2027. This dynamic creates a practical consequence for the administration’s decision to maintain the investigation—it prevents the replacement of the current Fed chair and maintains uncertainty about Fed leadership during a period of significant economic importance.

Market Response and Global Implications

The Powell investigation has implications extending beyond Congressional-executive branch tensions to affect global financial markets and international confidence in Federal Reserve independence.

Markets quickly responded to news of the investigation with concern: the dollar fell, gold prices rose, and Treasury rates climbed as investors interpreted the investigation as signaling erosion of Fed independence. These market movements reflect sophisticated investors’ understanding that Federal Reserve independence directly affects policy credibility and economic outcomes.

If international investors believe the Fed will make monetary policy decisions based on presidential preference rather than economic evidence, they will reassess their confidence in Federal Reserve policy and in dollar-denominated assets. This could drive up longer-term interest rates—the rates that most significantly affect American borrowing costs for mortgages, business investment, and government debt. Presidential pressure on the Fed to lower rates could result in higher rates as markets lose confidence in Fed independence.

Congress created the Federal Reserve as an independent agency as a foundational commitment underlying the global financial system. When Congress protects Federal Reserve independence, it’s also protecting American economic credibility internationally and the value of dollar-denominated assets held by investors worldwide.

Congressional Responsibility and Next Steps

The Powell investigation forces Congress to confront a question about its own authority and responsibility: What role does Congress play in defending the institutions it creates when the executive branch threatens their independence?

This is a structural constitutional question about the separation of powers and Congressional authority over the executive branch. Congress designed the Federal Reserve as an independent agency and has repeatedly defended that independence through legislation. The Banking Act of 1935 reflected Congressional judgment that monetary policy requires insulation from electoral pressures and presidential control. Yet the Powell investigation reveals a gap in statutory law: while Congress has protected the Fed from direct presidential control over interest rates, Congress has not fully protected the Fed from prosecutorial pressure.

Congress has multiple options for responding. In the immediate term, the Senate can use its confirmation authority to create political consequences for maintaining the Powell investigation, preventing replacement of Fed leadership until the investigation is resolved. For longer-term protection, Congress could enact a Federal Reserve Independence Act containing statutory protections adapted from international models: explicit protection for Congressional testimony, procedural requirements before investigating Fed officials, strengthened “for cause” removal standards, enhanced independence protections, and requiring the administration to tell Congress before taking action.

Such legislation would face constitutional challenge, but it would clarify Congressional intent and establish statutory language for courts to interpret. These options share a common principle: Congress, which created Federal Reserve independence through statute, retains authority to defend that independence through statute.

The Powell investigation will likely be resolved within months. But the constitutional framework Congress develops in response will shape how future administrations interact with the Federal Reserve and whether future Congresses can effectively defend Federal Reserve independence from executive pressure. That framework will determine whether the Banking Act of 1935’s vision of an independent central bank remains meaningful—or whether it becomes another statutory protection that a determined President can work around through creative use of prosecutorial power.
