Sen. Bob Casey Faces Pressure to Concede After Election Defeat

Despite a significant lead by Republican Dave McCormick, Bob Casey continues to challenge the election results in Pennsylvania.

Dave McCormick has been declared the winner of the Pennsylvania Senate race, leading by over 35,000 votes.
Sen. Bob Casey has not conceded, citing the need to count remaining provisional and overseas ballots.
Casey's refusal to concede is seen by some as an attempt to raise funds and possibly challenge the results in court.
The Associated Press and multiple sources have called the race for McCormick, with a margin just over the automatic recount threshold.
Senate Majority Leader Chuck Schumer initially withheld McCormick's invitation to Senate orientation, but later relented.
