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.
