U.S. President Donald Trump’s team is reviewing new contenders to lead the Federal Reserve once Chair Jerome Powell’s term ends in May, including a longtime economic consultant and a past regional Fed president, the Wall Street Journal reported on Friday.

The 10 or so people on the newly expanded list include former St. Louis Fed President James Bullard and Marc Sumerlin, a former economic adviser to President George W. Bush, WSJ said, citing officials. Trump last week said he had narrowed the list to four.

National Economic Council director Kevin Hassett and former Fed governor Kevin Warsh remain under consideration, along with current Fed governor Christopher Waller, WSJ said. Reuters has previously reported that these three are candidates, but could not immediately verify the rest of the report.

Trump has been criticizing Powell all year for not cutting rates, building on disappointment with the Fed chief that emerged during his first term as president shortly after he elevated Powell to the Fed chair role.

It was not clear what a broader list of candidates would mean for the timing of an appointment. Treasury Secretary Scott Bessent is helping lead the search.
