As Pennsylvania's razor-thin U.S. Senate race heads to a recount, allies of President-elect Donald Trump have claimed Sen. Bob Casey is working to steal an election, drawing false parallels between Trump's efforts to overturn the 2020 election results and Casey's decision not to concede in his reelection bid as votes are tabulated.

Sen. Bob Casey is locked in a tight race with Dave McCormick in Pennsylvania. There will be an automatic recount of the votes, state officials say.

Senator Bob Casey, the Democratic incumbent, is an institution in Pennsylvania. His Republican opponent is David McCormick, the former chief executive of Bridgewater Associates, a large hedge fund. Mr. McCormick lost the Republican Senate primary in 2022 to Mehmet Oz.
