Republican businessman Dave McCormick on Thursday declared victory in the U.S. Senate race in Pennsylvania against his opponent, incumbent Sen. Bob Casey (D-PA).

With 99% of the votes counted, McCormick was up on the three-term Democrat by more than 30,000 votes following President-elect Donald Trump’s victory in the state.

“McCormick is up 30,679 votes with more to come, as ruby red Cambria County is still outstanding,” said Elizabeth Gregory, McCormick’s communications director.

“While votes continue to be counted, any way you slice it, Dave McCormick will be the next United States Senator from Pennsylvania,” she added.

Casey has faced growing calls from Republican senators to concede the race since he does not appear to have a shot at overtaking McCormick in the vote count.

Sen. Bill Hagerty (R-TN) also posted on X that it was time for Casey to concede: “Bob Casey’s campaign website says he ran to ‘protect our democracy.'”

“Now’s his chance by honoring the will of Pennsylvania voters,” he said. “He lost. He knows he lost. He needs to concede to Senator-elect McCormick.”
