President Donald Trump on Tuesday fired the entire Commission of Fine Arts, a six-member independent agency that was expected to review the president's plans to build a Trump arch in Washington, D.C., according to a new report.

The Washington Post reported on Tuesday that the commission is a mix of urban planners and architects who were selected by President Joe Biden. Several of the members' terms extended beyond 2028, according to the report.

“On behalf of President Donald J. Trump, I am writing to inform you that your position as a member of the Commission on Fine Arts is terminated, effective immediately,” reads an email reviewed by The Post.

The commission's termination happened as Trump continues his plans to build a massive ballroom where the East Wing of the White House once stood. The project was initially supposed to cost around $200 million, and the president said it would minimally impact the East Wing.

Now, the project is expected to cost north of $350 million, according to estimates.

Trump has also said the project will be completely funded by private dollars, which has raised concerns for some ethics experts.

"The Commission on Fine Arts has traditionally reviewed major projects at the White House, but Trump may sidestep its review of his ballroom, citing historical precedent, architectural experts said," the report reads in part. "During a 1947 battle with President Harry S. Truman, who sought to add a balcony to the White House, CFA’s then-chairman said the panel could serve only in an 'advisory' role to the president. Truman ultimately proceeded with his plans, setting an example that Trump appears poised to follow."
