"What have I learned about our president? He's curious, he asks questions, and he knows no fear," Graham said in his remarks at the South Carolina Republican convention, as first reported by The Washington Examiner.

"He calls me when I'm asleep and he calls me after I go to bed. I wish he would rest more. I gave him my phone number. So far so good," he added.

Graham also defended Trump from recent criticism.



"And he's under siege unlike any president I've ever seen in my entire life," Graham said. "They don't believe he won; I do. Now Obama was somewhat hard for us, but I thought we were somewhat respectful."



"Let me tell you that you have a commander in chief that's not going to let this country get walked over anymore."

During the 2016 election, Graham was a frequent critic of Trump, often blasting the president for his policy toward Russia.
