2020 United States elections

U.S. Rep. Scott Perry and U.S. Senator Josh Hawley of Missouri object to Pennsylvania's electoral college votes, forcing a second vote to accept or reject the objection. This comes after the House and the Senate defeated a similar objection to Arizona's electoral college votes from Rep. Paul Gosar and Senator Ted Cruz. The Senate and the House both vote to reject the objection, allowing Joe Biden and Kamala Harris to receive the state’s electoral votes.
