President Donald Trump is considering many candidates to head up the Federal Reserve and has soured on nominating his top economic adviser Gary Cohn to lead the U.S. central bank, according to sources close to the White House and an administration official.

Two sources said Trump remained upset with Cohn, a former Goldman Sachs president, for criticizing his response to the violence sparked by a white supremacist rally in Charlottesville, Virginia, last month.

A White House official said Cohn remained an essential player in Trump’s push for tax reform.

Another administration official said Trump was “considering several candidates” for the Fed.

Fed Chair Janet Yellen’s term expires in February.

Trump was widely criticized for blaming “many sides” for the Charlottesville violence, and Cohn stood with him during a news conference at Trump Tower in New York days after the rally when the president said there “very fine people” on both sides
