The Globe and Mail reports in its Thursday edition that President Donald Trump has threatened to fire Jerome Powell if he remains at the Federal Reserve after his term ends on May 15. A New York Times dispatch to The Globe reports that this comes amid a criminal probe that could delay the confirmation of Mr. Powell's successor, Kevin Warsh. While Mr. Powell's chair term ends soon, he can temporarily serve until Mr. Warsh is confirmed. The effort to confirm Mr. Warsh has been complicated by the Justice Department's investigation into Mr. Powell and the costly renovations at the Fed's headquarters. Mr. Trump noted that the inquiry is not only about the $2.5-billion (U.S.) project but also about Mr. Powell's "incompetence." Mr. Powell has blasted the investigation as a pretext to pressure the Fed to lower borrowing costs. Mr. Trump's decision to pick another fight with Mr. Powell at a moment when the fate of his choice for chair is already in limbo runs counter to recent signals sent by top administration officials and senior Republicans. Treasury Secretary Scott Bessent said Tuesday that "we want Kevin Warsh in as soon as possible." Federal prosecutors have faced a litany of legal setbacks in their pursuit of the case.
