Graham was one of the Republicans candidates that Trump defeated in the primary. He has also been a consistent foil for the president. Graham joked that he might be on Trump’s “kill list.”

“I don’t know if I’m on the kill list or not, that would be good to know,” Graham told CBS before the inauguration.

At his first press conference after the election, Trump mocked Graham, a Russia hardliner. “He is going to crack that one percent barrier one day,” Trump said, before adding Graham “is a nice guy.”
