The Powell Investigation Creates a Complicated Ramp for Warsh's Path to the Federal Reserve

President Trump’s effort to accelerate Kevin Warsh into the Federal Reserve chairmanship faces an unexpected barrier: the very investigation his administration has launched against the incumbent Fed chief Jerome Powell. Warsh would typically assume the chairman role when Powell’s term concludes in mid-May, but a criminal probe by Trump’s Justice Department into Powell’s management of building renovations at the central bank has created political gridlock that could delay this transition.

The investigation, which many view as unprecedented interference in Fed affairs, has galvanized unexpected opposition within Republican ranks. Senator Thom Tillis, whose vote on the Banking Committee is crucial for any Fed nomination to advance, has made his position unambiguous: no confirmation vote will proceed until the Powell investigation reaches resolution. In recent interviews, Tillis has characterized the DOJ’s legal action as an assault on the Fed’s institutional independence, a position shared by other GOP lawmakers who distinguish between Trump’s public criticism of Powell and the more serious step of criminal prosecution.

Senate Republicans Block the Fast-Track Path

Tillis holds considerable leverage. As a moderate within his party and a swing voter on the Banking Committee, he has signaled resolve in opposing any Fed nominee—even one as qualified as Warsh—while the Powell probe continues. His blockade reflects genuine concerns about executive overreach, and he enjoys surprising support from Democratic colleagues on the committee who have also expressed alarm about the investigation’s implications for central bank independence.

The Republican senator’s position has proven remarkably durable. When pressed by reporters near Capitol Hill, Tillis reiterated his stance, using forceful language to describe the DOJ action as “baseless” and declaring that the prosecution process must terminate before he reconsiders his opposition. This puts Trump in a difficult position: his own Justice Department’s actions are now obstructing his ability to reshape Fed leadership according to his preferences.

Trump’s Vendetta Against Powell Complicates the Timeline

Rather than stepping back, the Trump administration has doubled down. In recent days, the president again assailed Powell as a “crook” over the building renovation matter, suggesting the situation involved either “incompetence or outright theft.” Trump has even indicated willingness to wait until Tillis’s scheduled retirement in January 2027 before pushing Warsh’s nomination through the Senate, a prospect that opens uncomfortable questions about interim Fed leadership.

This political stalemate carries economic consequences. The administration’s underlying rationale for installing Warsh involves shifting Fed policy toward interest-rate reductions that could stimulate growth ahead of November’s midterm elections. With Republican control of Congress at risk due to voter concerns about economic conditions, the delays in implementing a more dovish monetary stance become increasingly problematic for Trump’s legislative agenda.

The White House Searches for an Exit Strategy

Recognizing the impasse, senior administration officials have begun signaling urgency about resolving the Powell situation. Kevin Hassett, director of the National Economic Council, stated publicly that the Senate gridlock “is an issue that should get resolved quickly.” Senate Majority Leader John Thune echoed this concern, indicating that “closure on the Powell thing” needs to happen rapidly. Yet despite these rhetorical signals, there is scant evidence the White House is actively pressuring the Justice Department to abandon its prosecution.

Deputy Attorney General Todd Blanche stated at a press conference that the timing of Trump’s Fed nomination decision would not influence the DOJ’s investigative timeline. A White House official, speaking anonymously, asserted that the president is not directing prosecutors to halt their work. Treasury Secretary Scott Bessent previously suggested that if the Fed’s response to subpoenas proved satisfactory, the DOJ could “move forward,” but he has since defended the investigation’s legitimacy, leaving the administration’s true position ambiguous.

Legal Complications Could Persist Even With a Resolution

An intriguing complication emerges from legal expert analysis. Paul Tuchmann, a former federal prosecutor now at Wiggin and Dana, observed that merely ceasing the investigation might not fully protect Powell or reassure Tillis. “Unless you explicitly tell me that the criminal investigation is closed, it’s very hard to get that comfort that the prosecutor isn’t going to change their mind,” he explained. This suggests that even an abrupt DOJ withdrawal could leave Powell exposed to resumed legal action by future administrations or prosecutors.

The uncertainty extends to questions about who would lead the Fed if Warsh remains unconfirmed past mid-May. That decision—whether the White House or the Fed’s Board of Governors would appoint a temporary chairman—remains a largely unresolved legal question. The 2022 installation of Powell on a “pro tempore” basis offers limited guidance, as his eventual confirmation was considered assured and generated minimal scrutiny.

The Broader Stakes for Fed Independence

Beyond the immediate confirmation battle, the Powell investigation has crystallized broader concerns about political pressure on monetary policy. Investors have long worried that Trump’s campaign to browbeat the Fed into rate cuts represents dangerous politicization of banking decisions. Powell, for much of his tenure, largely absorbed Trump’s criticism without public response. But after learning in January that grand jury subpoenas had been served, Powell recorded a forceful video statement asserting the Fed’s commitment to independence, marking a notable escalation in the central bank’s pushback.

The investigation has attracted bipartisan criticism within Congress, where Fed independence traditionally enjoys cross-party support. Democratic Leader Chuck Schumer has declared that Warsh’s nomination should remain stalled until Trump abandons what he terms a “vendetta.” Republican Senator Lisa Murkowski has voiced backing for the Tillis blockade, creating a potential coalition that could indefinitely halt any new Fed chair confirmation if both parties align against Trump’s approach.

The unresolved question now centers on whether Trump will engineer an exit strategy from his own Justice Department’s prosecution—and whether such a reversal would even suffice to clear Warsh’s path to leadership of the central bank.
