Explanation of 1/6/21 Electoral Certification, by Emily Brooks, Washington Examiner:Sen. Ted Cruz and Rep. Paul Gosar led an objection to counting Electoral College votes from the state of Arizona, the first formal objection to state results in a series of moves that will delay the certification of Joe Biden as the winner of the 2020 presidential election over President Trump. Cruz is advocating for an `emergency 10-day audit` of election returns in disputed states. The usually ceremonial joint session of Congress that convenes to count and accept Electoral College votes will be put on hold as the House and Senate separately debate the objection.
