House Speaker Nancy Pelosi announced that Congress will take the steps to establish a Sept. 11-type commission to investigate the insurrection at the U.S. Capitol.

"Now, as always, security is the order of the day: the security of our country, the security of our Capitol which is the temple of our democracy, and the security of our Members," she wrote in a letter to her Democratic colleagues.

Retired Lt. Gen. Russel Honoré was appointed to issue a report on Capitol security following the riot.

"It is clear from his findings and from the impeachment trial that we must get to the truth of how this happened," Pelosi's letter continued. "To protect our security, our security, our security, our next step will be to establish an outside, independent 9/11-type Commission to 'investigate and report on the facts and causes relating to the January 6, 2021 domestic terrorist attack upon the United States Capitol Complex … and relating to the interference with the peaceful transfer of power, including facts and causes relating to the preparedness and response of the United States Capitol Police and other Federal, State, and local law enforcement in the National Capitol Region.'"
