U.S. Attorney Jeanine Pirro said Friday that she is dropping her investigation into Federal Reserve Chair Jerome Powell over the cost for renovations at the central bank, a move that could clear a path for the Senate to confirm Kevin Warsh as Powell’s replacement. 

“I have directed my office to close our investigation as the IG undertakes this inquiry,” Pirro said in a post on social media platform X. “Note well, however, that I will not hesitate to restart a criminal investigation should the facts warrant doing so.”

She said the Federal Reserve’s inspector general has been asked to scrutinize the renovation, saying the cost overruns ran into “the billions of dollars.” 

Pirro is the U.S. attorney for the District of Columbia. Her investigation into Powell and the cost overruns led Sen. Thom Tillis, R-N.C., a member of the Senate Banking Committee, to say he wouldn’t support any Fed nominee until the probe was dropped. His opposition would leave the committee tied if all the Democrats also oppose Warsh, which would prevent the nomination from advancing.

Tillis also said he considers Warsh a qualified nominee. Powell’s term as chair ends on May 15. 

“Let’s get rid of this investigation so I can support your confirmation,” Tillis said at Warsh’s hearing before the Senate Banking Committee on Tuesday.

Senate Majority Leader John Thune, R-S.D., said Wednesday that the Banking Committee would provide “accountability” for the investigation into the Fed renovations in an attempt to move the Warsh nomination ahead.

“The IG has the authority to hold the Federal Reserve accountable to American taxpayers,” Pirro posted. “I expect a comprehensive report in short order and am confident the outcome will assist in resolving, once and for all, the questions that led this office to issue subpoenas.”

Senate Banking Committee ranking member Elizabeth Warren, D-Mass., criticized the handoff of the investigation to the Fed IG.

“This is just an attempt to clear the path for Senate Republicans to install President Trump’s sock puppet Kevin Warsh as Fed Chair,” Warren said in a statement. “Let’s be clear what the Justice Department announced today: they threatened to restart the bogus criminal investigation into Fed Chair Powell at any time while failing to drop their ridiculous criminal probe against Governor Lisa Cook.”

She was referring to Trump’s attempt to fire Fed Governor Lisa Cook. Cook sued, and the case is now being considered by the Supreme Court.
