Congress will establish an “outside independent” commission to investigate the attack on the US Capitol by the supporters of Donald Trump, House Speaker Nancy Pelosi said.
She said in a letter to lawmakers that the commission would be modeled on the inquiry into the 11 September 2001 attacks on New York and the Pentagon.
“We must get to the truth of how this happened,” she said.
Pelosi said that retired US Army Lt Gen Russel Honoré had, over the past few weeks, been assessing the security needs of the Capitol in light of the attack.
She also said that the commission “would investigate and report on the facts and causes” of the attack; “the interference with the peaceful transfer of power”; and the “preparedness and response” of both the Capitol police and other branches of law enforcement.
She added that, based on Lt Gen Honoré’s initial findings, Congress needed to allocate additional funding to “provide for the safety of members and the security of the Capitol”.
A group of House Republicans wrote to Nancy Pelosi on Monday. In the letter, they complained that their party had not been consulted regarding the general’s security review.
They also demanded to know what instructions she gave to secure the Capitol before January 6.
Former President Donald Trump was acquitted by the Senate of backing the violence.
