Protesters supporting Donald Trump swarmed the US Capitol on Wednesday, putting it on lockdown, as Vice President Mike Pence rebuffed the president’s demand to overturn his loss to Democrat Joe Biden and the Senate’s Republican leader denounced a bid in Congress to undo the election outcome. Times Live reports that the demonstrations flared as lawmakers met inside to formally certify Biden’s victory over Trump in the Nov. 3 election with Trump supporters overturning barricades and streaming inside the building while law enforcement authorities struggled to maintain order. “We will never give up,” Trump earlier told thousands of cheering supporters on a grassy expanse near the White House called the Ellipse, “we will never concede”.
