It’s disclosure day.

The White House will begin the release of long-awaited UFO files on Friday – months after President Trump ordered top administration officials to get the ball rolling on the out-of-this-world intel, The Post has learned.

The timeframe was disclosed during a West Wing meeting on Thursday attended by Rep. Tim Burchett (R-Tenn.), a member of the House Oversight Committee’s task force on the declassification of federal secrets.

“It’s going to start tomorrow. It’s going to have some stuff in there from pilots, and maybe one video,” Burchett told independent journalist Jeremy Corbell in a conversation shared with The Post.

“Pilot materials” could refer to encounters that American military pilots had with UFOs while on active duty, according to sources.

The first release will not include the 46 UFO videos that Congress has demanded the Department of War release to the public.

Successive releases will come out in weekly tranches — markedly distinct from the data-dump method of the JFK and Epstein files.

Burchett noted that some in Congress are still resisting the release — but he’s confident Trump’s promise to release the files will be kept.

“The deep state is not turning up this stuff easy, but [Trump’s] following through with it,” the lawmaker told Corbell via phone.

“He’s doing what he said he’s going to do. He’s fighting this thing, and he’s bringing stuff out,” Burchett said, adding, “I’m saying thank you President Trump for keeping your word.”

The Post has reached out to Burchett for comment.
