In the Trump administration's war with Federal Reserve chair Jerome Powell, there is a new front — ostensibly about beehives and rooftop gardens, but really a fight for control of the U.S. central bank.

Office of Management and Budget Director Russell Vought accused Federal Reserve Chair Jerome Powell on Thursday of an “ostentatious” overhaul of the independent agency’s fiscal headquarters amid an increasingly aggressive campaign by President Trump to get Powell to step down from the job.

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.
