Federal Reserve Chairman Jerome Powell announced that he will remain on the Fed’s Board of Governors beyond the end of his term as chairman next month, breaking with tradition at the central bank and preventing President Donald Trump from quickly nominating his replacement.

Powell, who was holding his last press conference as Fed chairman, previously said he would remain on the Fed board until the Justice Department investigation into him ended. On Wednesday, he confirmed that he plans to remain on the board. While his term as chairman ends on May 15, his term as a member of the board runs until 2028.
