As President Trump railed against the FBI for potentially harboring bias against him, he has repeatedly badmouthed the place which the agency calls home, the J. Edgar Hoover Building in downtown Washington, D.C., and has expressed interest in overseeing a "revamp" effort, according to a report Sunday.

A real-estate magnate before he became commander in chief, Trump called the building "one of the ugliest buildings in the city" while remarking about its Brutalist architecture, a source told Axios.

Trump reportedly told chief of staff John Kelly that he wants to get involved with whatever construction project may happen and opposes moving the FBI out of Washington because it is located on "prime real estate."

"POTUS is always interested in building because he knows it better than anyone and has been very successful in it. He's found GSA to be on it, 'very impressive' and 'knowledgeable' are the phrases he has used," White House press secretary Sarah Sanders told Axios.

The FBI has not yet submitted a plan to Congress for a new building nor has Congress lined up any money for such a project.

The J. Edgar Hoover Building, completed in 1975, is located down Pennsylvania Avenue from the White House and is named after former FBI Director J. Edgar Hoover.
