NEW: Senator John Fetterman refuses to back down as Katie Couric continuously tries to get him to condemn Charlie Kirk. Couric: Do you think his body should have been flown on Air Force Two? Fetterman: I'd say that that was [Trump's/Vance's] choice. Couric: Did you have any issues now in hindsight over some of the things that Charlie Kirk said? ... Fetterman: Charlie engaging in debate would never justify what's happened. I just chose not to take the opportunity to argue his views after children lost their father in the most violent public way. Couric: I think some people might say Charlie Kirk's rhetoric was extreme ... People think his words lead to violence. Fetterman: I think we agree that we probably didn't agree with much of what he said. But I'm sure we both agree that you shouldn't execute them in public. It's remarkable when a man gets murdered and idiots like @katiecouric are most worried about condemning his rhetoric.
