100,000 - 200,000 extra/unregistered votes were added to the tallys in Pennsylvania for the 2020 election
In November 2020, Senator Doug Mastriano sent out a Tweet showing apparent discrepancies in numbers of votes mailed out vs returned, showing an extra 1,126,940 votes.
Later in December 2020, a group of Pennsylvania Republican lawmakers claim their analysis of 2020 election data shows over 200,000 more ballots counted than voters recorded as having voted, exceeding Biden’s margin of victory in the state. They argue this discrepancy, along with earlier concerns about mail-in ballot rules, drop box security, and poll watcher access, makes the presidential results uncertifiable. They allege the state’s election oversight is inconsistent, error-prone, and violates Pennsylvania’s election code. The lawmakers conclude that certifying the state’s presidential electors for Biden is premature and in error.
This was later repeated by Donald Trump:
Claims, refutations, and/or supporting information:
"Pennsylvania reports having mailed out 1,823,148 ballots, of which 1,462,302 were returned. Yet total main-in votes number 2,589,242? From where did the extra 2,589,242 - 1,462,302 = 1,126,940 votes come?"

A group of Republican lawmakers in Pennsylvania say 200,000 more votes were counted in the 2020 Election than voters (100% went to Biden). State Representative Frank Ryan said they found troubling discrepancies after an analysis of Election Day data.” @FoxNews This is far more votes than is needed by me to win Pennsylvania, not to mention hundreds of thousands of votes in other categories which increase my already big lead into a landslide. All other Swing States show likewise. WE NEED NEW & ENERGETIC REPUBLICAN LEADERSHIP. This can not stand....
