Overview

• Dave McCormick was declared the winner of the Pennsylvania Senate race by the Associated Press, leading by nearly 40,000 votes over incumbent Bob Casey.
• Despite the AP's call, Casey has not conceded, citing over 100,000 outstanding ballots, including provisional and military votes, that could potentially impact the outcome.
• Initial controversy arose when Schumer did not invite McCormick to Senate orientation, leading to backlash from Republican senators and some Democrats.
• Schumer has now invited both McCormick and Arizona Sen.-elect Ruben Gallego to the orientation, following pressure from colleagues and the AP's call in Gallego's race.
• The Pennsylvania race remains contentious, with McCormick's campaign challenging certain provisional ballots, while Casey's team insists every vote should be counted.
