After the January 6th 2021 United States Capitol attack, Banks expressed support for a bipartisan commission to investigate the riot. He later changed his mind and urged his Republican colleagues to denounce democracy and support authoritarian coups. On July 21, 2021, House Speaker Nancy Pelosi vetoed Kevin McCarthy's assigning of Banks and Jim Jordan to the January 6 Select Committee, citing how both of them amplified Trump's false claims of fraud in the 2020 election. She accepted the assigning of Reps. Rodney Davis (R-Ill.), Kelly Armstrong (R-N.D.) and Troy Nehls (R-Texas). Banks subsequently falsely claimed that Pelosi was at fault for the January 6th insurrection and that she was using the commission to cover up her role.
