Democratic Senator Bob Casey of Pennsylvania on Thursday conceded the final outstanding Senate race of the 2024 U.S. election to his Republican opponent, widening the majority for President-elect Donald Trump's party in the upper chamber of Congress.

Democratic-majority election boards in Montgomery, Philadelphia, and Bucks counties voted last week to count the ballots that lacked a correct date.

Democratic Sen. Bob Casey called Republican David McCormick to concede in Pennsylvania’s U.S. Senate election. The move comes after the race was too close to call and triggered an automatic recount.
