WATCH: Lindsey Graham Roasts His ‘Batsh*t’ Republican Colleagues

During a press dinner on Thursday night, Sen. Lindsey Graham (R-SC) let loose on the Republican party and the GOP presidential candidate, telling his party that it’s going to have to “up its game.”

Graham’s comments came during a dinner held by the Washington Press Club Foundation Dinner where lawmaker guests typically crack jokes about their own party, as well as lawmakers across the aisle.

During his speech, Graham lamented that Hillary Clinton is about to become president, blaming it on Republicans.

“How could that be? My party has gone batshit crazy,” he explained.

He then joked about how much Senate Republicans dislike Sen. Ted Cruz (R-TX).

“If you kill Ted Cruz on the floor of the Senate, and the trial was in the Senate, nobody could convict you,” he joked.

When it came time for Graham to joke and hurl insults at Donald Trump, the senator instead made some sobering remarks.

“I don’t know how I can best describe Donald Trump, but I can say this, that I don’t think he understands what makes America great. And I know I’m supposed to be funny, but I’m not really happy about where the country is right now,” Graham said. “I could make a million Donald Trump jokes, and I have. But our party and our country is going to have to up its game.”
