President Trump has fired six members of the U.S. Commission of Fine Arts — an independent agency that advises the president and Congress on design plans for monuments, memorials, coins and federal buildings.

As first reported by The Washington Post, the White House fired six commissioners; the chair position was vacant. The commissioners would have advised the president on the proposed White House ballroom and his plans for a monument similar to the Arc de Triomphe in Paris.
