During a speech to the Rotary Club in South Carolina's capitol, Sen. Lindsey Graham (R-SC) reportedly bragged about his relationship with Donald Trump — and said he called the president "crazy" when speaking with a foreign diplomat.

"If you don't think Trump's crazy, then you're crazy," Graham told the crowd, as flagged by the Charleston Post and Courier's Columbia bureau chief Andy Shain.

According to Shain, the South Carolina Republican also called Trump "volatile," "a genius" and "a handful," and responded to reports that Sen. John McCain (R-AZ) asked for Trump to not attend his funeral.

"I have no idea if that’s true," Graham told the crowd at the Columbia Rotary Club. "There’s a lot of things being said."
