Republican Dave McCormick has filed a lawsuit in connection to uncounted provisional ballots in his race against incumbent Democrat Bob Casey.

The suit is asking the Court of Common Pleas in Philadelphia to allow McCormick to make global challenges to large groups of provisional ballots that share the same deficiencies including missing signatures or lack of a secrecy envelope.

The Philadelphia Board of Elections is currently examining 15,000 to 20,000 provisional ballots.

NewsNation/Decision Desk HQ has not yet projected a winner in the race.
