President Donald Trump, after a tour of the Fed’s $2.5 billion renovation, said he didn’t want to fire Federal Reserve Chair Jerome Powell because of the plan’s cost overruns.

Donald Trump has been bullying Federal Reserve Chair Jerome Powell—calling him “too late,” insulting his intelligence, and trying to gin up a case that Powell spent too much on renovations of the agency’s headquarters as a pretext for firing him.

President Trump visited the Federal Reserve on Thursday afternoon as tensions rise over Fed chair Jerome Powell’s refusal to lower interest rates and his request for funds to renovate the property that house the nation’s central bank.
