As rioters swarmed the U.S. Capitol, Congress has been forced to abruptly halt deliberations over Republican challenges to Joe Biden’s presidential victory. Republicans in a joint session of Congress were mounting their first formal challenge to Biden’s election win.

Outside, meanwhile, demonstrators are protesting the joint session, which is to confirm Biden’s victory in the Electoral College. The typically routine proceeding, required by law, was anything but ordinary. The president’s Republican allies plan to object to several states’ election results. Many say they are heeding the pleas of the president’s supporters’ to “fight for Trump.”
