At least four people died on the US Capitol grounds Wednesday and 52 people were arrested after supporters of President Donald Trump stormed the Capitol in an unprecedented effort to stop Congress from certifying President-elect Joe Biden’s election victory, Metropolitan Police Department Chief Robert J Contee said.

The US Capitol had to be locked down Wednesday with lawmakers inside after protesters tore down metal barricades at the bottom of the Capitol’s steps and were met by officers in riot gear.  Some tried to push past the officers, who held shields, and the police could be seen firing pepper spray into the crowd to keep them back, even as the crowd shouted, “traitors”.  The violence soon moved inside the Capitol building, with reports of firing at the premises.

The US House of Representatives and Senate had met in a rare joint session to begin considering the certification of Electoral College results, that show Democrat Joe Biden defeated Trump.

DC Mayor Muriel Bowser announced she is extending the public emergency to 15 days, as a result of rioters overtaking the US Capitol building earlier today. This will take the emergency declaration until the day after President-elect Joe Biden's inauguration.

The mayor says that the people who stormed the Capitol, “sought to disrupt the Congressional proceedings relating to the acceptance of electoral college votes.”

“Persons are dissatisfied with judicial rulings and the findings of State Boards of Elections, and some persons can be expected to continue their violent protests through the inauguration.”
