Maj. Gen. William Walker said the Department of Defense took three hours to approve deploying the National Guard to the Capitol on Jan. 6 after a "frantic" request from Capitol Police.

Republican lawmakers want equal party representation on the panel to investigate the Jan. 6 attack on the U.S. Capitol.

The officials testifying Tuesday resigned in the wake of the Jan. 6 insurrection. Former Capitol Police Chief Steven Sund said, "None of the intelligence we received predicted what actually occurred."

The Jan. 6 insurrection at the Capitol exposed a number of security shortfalls at the seat of American democracy. Acting Chief Yogananda Pittman released a video statement Friday evening.

Steven Sund contradicts reports that help was not requested, saying security officials at the House and Senate rebuffed calls for assistance ahead of and during the attack on the Capitol.

Lawmakers took aim at top Capitol security officials the day after a mob of pro-Trump extremists breached the building and forced evacuations. Now top Capitol security officials have quit.
