Congress certifies Biden's electoral victory after Trump supporters storm the Capitol, with mail ballot counts contested to the end

Congress certified Joseph Biden's 306-232 Electoral College victory in the early hours of January 7, 2021, after Trump supporters broke into the Capitol and interrupted the count for six hours. Trump and allies had spent the preceding two months contesting mail ballot counts in Pennsylvania, Georgia, Arizona, Michigan, and Wisconsin — the five battleground states that decided the election. Courts rejected 60+ post-election lawsuits challenging mail ballot rules, and all five state election officials certified their results under legal pressure.
