A mob of people loyal to President Donald Trump stormed the Capitol on Wednesday, halting Congress’ counting of the electoral votes to confirm President-elect Joe Biden’s victory as the police evacuated lawmakers from the building in a scene of violence, chaos and disruption that shook the core of American democracy.

Around 2:15 p.m., as the House and Senate debated a move by a faction of Republicans to overturn the election results, security rushed Vice President Mike Pence out of the Senate chamber and the Capitol building was placed on lockdown after angry pro-Trump demonstrators surged past barricades and law enforcement toward the legislative chambers.

For a time, senators and members of the House were locked inside their respective chambers. Images posted on social media showed scenes of supporters violently tussling with the police as at least one person took to the rostrum of the House chamber to declare his support for Trump.
