Trump’s top budget adviser sent Powell a letter saying Trump is “extremely troubled” by the “ostentatious overhaul.” Two aides were named to a panel that plans to review the building plans.

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.

A key Trump official said Federal Reserve Chair Jerome Powell has “grossly mismanaged” the institution and demanded more information about the central bank’s renovation of its headquarters in Washington.
