Sen. Lindsey Graham (R-SC) has become one of President Donald Trump's staunchest supporters in Congress—a tireless defender of Trump agenda and character.

But, not so long ago, Graham was a skeptic of Trump who tried to hold his worst impulses in check.

Back in July 2017, Graham said there would be "holy hell to pay" if Trump fired Attorney General Jeff Sessions to quash the Robert Mueller probe and warned it would be "the beginning of the end of Trump's presidency."

On Thursday night, Fox News asked Graham about his old comments, making him visibly uncomfortable.

"When was that?" Graham said. "What year?"

"July of 2017," said anchor Martha MacCallum.

"Hehehehehehehehe," Graham said. "So... Hehe. Yeah... So, what I've been saying for months is that every president deserves an Attorney General they have confidence in."
