Congressman reveals hidden secret passageway from America's founding under Capitol floorboards

"Construction started in the 1700s and there are all sorts of little hidden passageways. As you saw, I just pulled this cover up, and you can see," Moore said in a video posted to his official congressional X account on Friday, showing a secret door in the floor of the Capitol. 

The U.S. Capitol's construction was commissioned in 1793, with President George Washington laying the cornerstone that same year. The original building was completed in 1826, with various expansions made across the decades, such as a visitor center that opened in 2008. 

"But the most interesting part of the room is underneath the floorboards," Moore posted to X. 

The North Carolina Republican opened a hidden door on the floor, revealing a dusty and historic staircase leading to what appeared to be another room below. 

The Army will hold a 250th anniversary of its founding next month with a planned parade that will stretch from Arlington, Virginia, to the National Mall.
