Key Facts

In a letter to House Democrats, Pelosi said former President Trump’s impeachment trial and the preliminary findings of retired Gen. Russel Honoré – who has been tasked with reviewing security failures during the attack – make clear that Congress “must get to the truth of how this happened.”

Pelosi said the “next step” to ensuring the security of Congress will be to “establish an outside, independent 9/11-type Commission” to investigate the “facts and causes relating to” the Jan. 6 attack.

The commission will also probe facts and causes relating to the “interference with the peaceful transfer of power,” as well as the preparedness and response of federal law enforcement and the military.
