The US Senate is preparing to vote on President Donald Trump’s nomination of Kevin Warsh to serve as chair of the Federal Reserve. Warsh has been nominated for a four-year term as chair and a 14-year term as a member of the Board of Governors, replacing Jerome Powell, whose term as chair ends in May. Powell is expected to complete his leadership term, though he could remain on the board until 2028.

Warsh previously served as a Fed governor under Presidents George W. Bush and Barack Obama from 2006 to 2011. His nomination now heads to the Senate, where it may face resistance from Democratic lawmakers concerned about preserving the Fed’s independence amid ongoing political tensions.
