“But the problem is,” he explained, “we’re now looking at what is a must-hold Republican Senate seat if the Republicans ever want to take the majority in the U.S. Senate.” Hannity then listed a series of elements of Barnette’s past that he deemed troubling, one of which was a January 2016 tweet in which she called then-President Barack Obama a “Muslim.”

“With six days left in this campaign, there are serious, real, open questions” about Barnette, Hannity said.

As for Oz, Hannity said, “I see him by far as the Republican candidate in this primary that will win the general election.”

With that, Hannity welcomed on Oz—whom the Fox host and former President Donald Trump have endorsed—to restate his case to Pennsylvania voters, who will head to the polls next Tuesday.

“I concur with your diagnosis. She is a mystery,” Oz said of Barnette. The controversial celebrity doctor then repeated many of the arguments that Hannity had just made, including his electability in the general election and how Barnette lost a 2020 House race in a district near Philadelphia.
