Biden brands Capitol violence 'insurrection,' demands Trump call off siege

President-elect Joe Biden on Wednesday denounced the storming of the US Capitol as an "insurrection" and demanded President Donald Trump go on television to call an end to the violent "siege." "At this hour, our democracy is under unprecedented assault," the veteran Democrat said in Wilmington, after hundreds of Trump supporters protesting his election defeat swarmed the Capitol building and put the nation's lawmakers at risk.
