For Republican lawmakers who usually move in lockstep with President Donald Trump, the Justice Department’s investigation into Federal Reserve Chairman Jerome Powell is quickly becoming an unexpected loyalty test, with many GOP lawmakers expressing some discomfort and some going so far as to vow to make efforts to replace Powell difficult.
Republican Sen. Thom Tillis of North Carolina — a member of the Senate Committee on Banking, Housing, and Urban Affairs — wasn’t concerned with any potential impropriety Powell may have committed by not accurately predicting the costs of Federal Reserve building renovations, as the DOJ is investigating. Tillis said it was “the independence and credibility of the Department of Justice that are in question.”
“If there were any remaining doubt whether advisers within the Trump Administration are actively pushing to end the independence of the Federal Reserve, there should now be none,” Tillis said.
While the unease that many Republicans are expressing is notable on its own, Tillis and some other GOP lawmakers are taking their discomfort a step further.
Tillis, who’s retiring at the end of 2026, said he would vote against any Federal Reserve nominee “until this legal matter is fully resolved” — including the looming vacancy to fill the chairman seat, which will be up for grabs when Powell’s term atop the Central Bank expires in May.
The Senate Banking Committee is composed of 13 Republicans and 11 Democrats, meaning if Tillis follows through with his ultimatum and joins all Democrats to oppose the next nominee, the panel would be deadlocked — holding up any Trump pick for the influential governing body.
And Tillis isn’t alone.
Republican Sen. Lisa Murkowski of Alaska called the Justice Department’s probe “nothing more than an attempt at coercion,” adding that Tillis was “right in blocking any Federal Reserve nominees until this is resolved.”
“The stakes are too high to look the other way: if the Federal Reserve loses its independence, the stability of our markets and the broader economy will suffer,” Murkowski said in a statement.
Other Republicans expressed similar displeasure with the DOJ’s subpoenas and the potential impact on the independence of the Federal Reserve, but no one was quite willing to take the same hardline stance as Tillis.
For instance, Republican Sen. Kevin Cramer of North Dakota said he does “not believe” Powell “is a criminal,” but he added that he is a “bad Fed Chair.”
“I hope this criminal investigation can be put to rest quickly along with the remainder of Jerome Powell’s term,” Cramer said.
But when pressed on what action he would take to push back on the investigation, which he said he’s “not crazy for,” Cramer said he didn’t plan “to get super involved.”
“There are three branches of government and that’s not mine,” he said.
It was a similar story with many other Republicans. Sen. Mike Crapo, R-Idaho, said he’d “like to see this resolved as quickly as possible,” adding that it’s important the Fed remain “free of political influence.” But he didn’t say what he might do to maintain a Federal Reserve that’s free of that political influence.
Sen. Dave McCormick of Pennsylvania, who sits on the Senate Banking Committee, said he didn’t think Powell was “guilty of criminal activity.” But again, he didn’t call out Trump, and he didn’t say he’d do anything to address this criminal probe.
Sen. John Kennedy, R-La., another member of the Senate Banking Committee, seemed to take issue with the investigation, but he suggested his concern was that, contrary to the president’s wishes, the grand jury subpoenas might increase interest rates.
“If you wanted to design a system to cause interest rates to go up and not down, you would have the Federal Reserve of the United States and the Executive Branch of the United States get into a pissing contest. We don’t need it,” Kennedy said. “We need it like we need a hole in our head.”
“Everybody needs to take their meds and step back a little bit,” he added.
Still, other Republicans tried to avoid weighing in at all — or simply deferred to the Department of Justice.
Sen. Josh Hawley, R-Mo., said he didn’t know enough to comment. Sen. Rick Scott, R-Fla., said he didn’t know “enough about the facts.” And Sen. Markwayne Mullin, R-Okla., concluded that if the DOJ was taking this step, “there’s got to be a legal reason for it, and so I think we just let it play out.”
The GOP pushback broke out shortly after The New York Times reported Sunday that the Justice Department had opened a criminal investigation into Powell, a frequent target of Trump’s ire over stubborn interest rates. For months, the president has publicly pressured the Central Bank chairman to bring down borrowing rates, flirting with outright firing him — an unprecedented move in and of itself.
The Fed has lowered interest rates three times during Trump’s second term, the most recently in December. But Trump is concerned that Powell isn’t bringing rates down faster and by more.
Ostensibly, the purpose of the investigation is to probe whether Powell lied to Congress when he testified about the renovation of the Federal Reserve’s headquarters in Washington, D.C. The project, which first received approval in 2017, seeks to revamp two Fed buildings that, according to the Central Bank, have not been renovated since the 1930s.
