On Wednesday, a large group of Trump supporters stormed the Capitol building in a bid to protest lawmakers who were certifying the presidential election results. During the violence that saw 5 killed, Trump supporters clashed with police and damaged property before seizing portions of the rotunda and the inauguration stage. The event is the most significant breach of the US Capitol grounds since the British set fire to the structure in 1814.
