The lawsuit, filed in federal court in Harrisburg, accuses state and county officials of grossly mismanaging the process of voting by mail and shrouding the tabulation of mail ballots in secrecy by denying Republican monitors sufficient access to inspect them as they were being counted.

Though many of its claims have already been presented and litigated in courts across the state — many which ruled against the president’s campaign — the new 86-page filing presented GOP lawyers' most comprehensive case yet in attempting to undermine public confidence in Pennsylvania’s election results.

“The very officials charged with ensuring the integrity of the election in Pennsylvania have so mismanaged the election process that no one — not the voters and not President Trump’s campaign — can have any faith that their most basic rights under the U.S. Constitution are being protected,” wrote attorneys Ronald L. Hicks Jr. and Carolyn B. McGee, of Pittsburgh, and Linda Kerns, of Philadelphia. “Nothing less than the integrity of the 2020 presidential is at stake in this action.”
