Sen. Tim Scott on Wednesday said he hopes the federal investigation into Federal Reserve Chair Jerome Powell “goes away” so the Senate can take up the nomination of Kevin Warsh, President Donald Trump’s pick to replace the head of the U.S. central bank.

“That proceeding going away allows for us to get the Fed fully functioning, back on target,” Scott, who chairs the Senate Banking, Housing and Urban Affairs Committee, said during an appearance on CNBC’s “Squawk Box.”

Sen. Thom Tillis, R-N.C., has vowed to hold up any Fed nominees until a federal criminal investigation into Powell is resolved. Trump floated the idea of firing Powell last year and lashed out at the Fed chair for refusing to cut interest rates to the extent he desired. Powell has denied any wrongdoing and has said he is being targeted for refusing to accede to Trump’s demands.

Powell was expected to testify before Congress on Feb. 11, but missed that date because of the federal probe, Scott said.

“I had a conversation with Jay about his testimony,” Scott said. “I recommended that he come before the committee.”

“At this point he is more concerned about the criminal proceeding ,” he said. “And I get that.”

The Fed did not immediately respond to a request for comment.

Tillis is otherwise supportive of Warsh, who Trump nominated for the role in January, but doubled down on his blockade after meeting with the Fed nominee on Tuesday.

“This is not about people, it’s about process,” Tillis said. “I think this is a foul.”

“This is about this is bedrock principle of Fed independence,” Tillis told reporters Tuesday. “I have no earthly idea what the market reaction would have been if suddenly the perception is that the Fed chair serves at the pleasure of the president.”

Sen. Kevin Cramer, R-N.D., another Banking committee member, told CNBC earlier Wednesday he sees no reason why some Democrats won’t support Warsh’s nomination.

“There’s really no reason by anything from he’s ever said or that he’s done that, that Democrats shouldn’t support his nomination,” Cramer, who was scheduled to meet with Warsh on Wednesday, said. “They’re going to be rigorous, of course, in their interviewing of him and and the cross examination … when his hearing takes place. But I think we should be on track to get him across the finish line so that there’s no gap between … the end of Jay Powell’s term and the beginning of the new term.”

The investigation into Powell is in part based on testimony Powell gave to the Senate Banking committee last year. Scott has said in the past that he did not believe Powell committed a crime in his testimony, sentiment he repeated Wednesday. He said the Senate would begin confirmation hearings for Warsh “as soon as possible.”

“At the end of the day … when he was before the committee he definitely was unprepared,” Scott said of Powell. “I think he was woefully unprepared. But he did not commit a criminal act when he was before the committee.”
