About 24 hours before the January 6 Capitol attack, a Republican member of Congress, Barry Loudermilk, led an unofficial tour through the House office buildings, passing by the security checkpoints located at the entrances to the tunnels leading towards the Capitol building.
The tour included a man who took photos of the tunnel entrances and the US Capitol police checkpoints, and then joined thousands of Donald Trump supporters the following day to march on the Capitol from the rally on the Ellipse.
