Kevin Warsh, President Donald Trump’s pick to lead the Federal Reserve, has promised a “regime change” at the central bank, a goal that could include overhauling or cutting staffing.

Warsh, 55, has been nominated to replace outgoing Fed Chairman Jerome Powell after Powell’s term ends in May. There has been much speculation about how Warsh will conduct monetary policy and shrink the Fed’s balance sheet. Less noted, though, is that he has signaled he would implement personnel changes at the central bank as well.
