On 6 January, thousands of Trump supporters violently besieged the Capitol in a bid to prevent Congress from certifying Joe Biden's election victory.
The protesters attacked police with metal pipes and chemical irritants, damaged property, seized the inauguration stage, and occupied the rotunda inside the Capitol building.
