Fitzpatrick, a four-term congressman and former FBI agent, represents a district based in Bucks County that Democrat Joe Biden carried in the 2020 presidential election.
He defeated Democrat Ashley Ehasz, a retired Army helicopter pilot who lost to Fitzpatrick by nearly 10 percentage points in 2022. The Associated Press declared Fitzpatrick the winner at 1:23 a.m. EST.
Fitzpatrick was just one of 16 Republicans running for reelection in a district carried by Biden in 2020. But Fitzpatrick, who took over the seat from his late brother, has a potent winning formula that has included his family's name recognition and inroads into traditional Democratic voting districts.
He was endorsed by top-tier labor unions, ran a digital ad calling himself the "No. 1 most bipartisan congressman" and contended that he backs abortion rights, despite Ehasz's contentions otherwise.
