Asked Sunday about Trump’s mood and expectations ahead of arguments that are set to begin Tuesday, Graham, a close ally of the President, said Trump is optimistic the trial will go in his favor.

“His mood is to go to the State of the Union with this behind him and talk about what he wants to do for the next, rest of 2020 and what he wants to do for the next four years,” Graham said during the interview with Fox News. “He is very much comfortable with the idea that this is going to turn out well for him.”

“The one thing he talks to me constantly about is, what does the next president do after this if this is successful? He does not want to legitimatize the attack on the presidency.”
