The Trump administration’s intensifying campaign against Federal Reserve Chair Jerome Powell hit a boiling point Thursday.

The Federal Reserve's] hesitancy to cut rates, I think, is actually … quite a mark against them,” former Fed governor Kevin Warsh said.

The White House accuses the Fed chair of potentially "violating the law" in his renovation of the central bank's Washington, D.C., headquarters.

WASHINGTON, July 13 (Reuters) - U.S. President Donald Trump has the authority to fire Federal Reserve Chair Jerome Powell for cause if evidence supports that, White House economic adviser Kevin Hassett said on Sunday and that the Fed "has a lot to answer for" on renovation cost overruns at its Washington headquarters.

The president floated the idea of firing the Fed chief to lawmakers, then said such a move was "very unlikely."
