The U.S. Capitol Police arrested a group of staffers with CBS's "The Late Show With Stephen Colbert" after they allegedly illegally entered a U.S. House of Representatives office building on Thursday night, Fox News has learned.

The group of seven people were arrested in the Longworth House Office Building after being escorted out of the Jan.

6 committee hearing earlier in the day because they did not have proper press credentials, according to sources.

The same group resurfaced later on Thursday night after the Capitol complex was closed to public visitors and Fox News is told that they took videos and pictures around the offices of two Republican members of Congress, Minority Leader Kevin McCarthy R-Calif. and Rep. Lauren Boebert, R-Colo.

A senior source in the U.S House of Representatives told Fox News that seven individuals associated with Stephen Colbert's show were arrested.

Fox News is told that the "The Late Show With Stephen Colbert" team applied to get press credentials for the Jan. 6 hearing, but the House Radio/TV Gallery rejected the request because they are not considered "news."

The issue didn't go to the Radio/TV Correspondents Association, which usually handles credentialing.

In addition to a regular Capitol Hill press pass, a special "overlay" is required for members of the press who want to be in the room for the Jan. 6 Committee hearings.

Members of Colbert's team could have been in House office buildings if they were invited, which they were.

Fox News is told that Colbert's team conducted interviews earlier on Thursday with members of the Jan. 6 Committee, including Reps. Adam Schiff, D-Calif.
