Democratic House Speaker Nancy Pelosi has announced the creation of a committee to investigate the Capitol Hill riot in January this year.
Mrs Pelosi said the Democratic-led committee would aim to "establish the truth of that day and ensure that an attack of that kind cannot happen".
The move comes after Senate Republicans blocked a bill to establish a bipartisan commission into the attack.
Allies of former President Donald Trump said a commission was not necessary.
His supporters stormed Congress in Washington DC on 6 January in a failed bid to overturn the certification of Democratic President Joe Biden's election victory in November.
The riot left five dead, including a Capitol police officer.
The assault led to the political impeachment and acquittal of Republican Mr Trump, who was accused by lawmakers of inciting the riot.
