Fact-checking claims in the John Fetterman-Mehmet Oz Pennsylvania U.S. Senate race

Pennsylvania Lt. Gov. John Fetterman and celebrity doctor Mehmet Oz are locked in a tight race for a U.S Senate seat that could determine which party controls that chamber in 2023.

Multiple polls show Fetterman, a Democrat, and Oz, a Republican, neck and neck in a heated battle for the seat held by retiring Republican Sen. Pat Toomey. Observers rate the race a toss-up.

Both candidates brought in heavy hitters to boost their chances in the final weekend before the Nov. 8 election.

Former President Donald Trump stumped for Oz on Nov. 5 in Latrobe, while also teasing another presidential run in 2024. Trump told the crowd a Fetterman win "will mean death and despair" for the state’s residents and that "Dr. Oz is the only one who can stop him."

Fetterman, meanwhile, brought in the current and former president to tout his candidacy.
