Will Congress Block Certification of Biden's Victory? Patsy Widakuswara Lawmakers from the U.S. Senate and House of Representatives are scheduled to meet Wednesday in a joint session of Congress to count and certify electoral votes based on the result of the November presidential election. This usually routine and ceremonial function -- a final step after the Electoral College officially elected Joe Biden on December 14 -- has turned into a litmus test of Republican lawmakers' loyalty to President Donald Trump. More than 100 Trump loyalists are set to challenge certification. Here's what we can expect from the meeting. What usually happens? Under the [1]12th Amendment, both chambers must meet to officially count and certify the Electoral College results from all 50 states and the District of Columbia. Representatives of the Democratic and Republican parties in the Senate and House are appointed as "tellers" from each chamber. Vice President Mike Pence, in his capacity as president of the Senate, presides over the joint session. If he cannot preside, the longest-serving senator in the majority party, in this case, Republican Sen. Chuck Grassley of Iowa, leads the session as the Senate president pro-tempore.
