Republican South Carolina Sen. Lindsey Graham unloaded on his party and the remaining Republican presidential candidates Thursday, joking that the GOP "has gone bats--- crazy" and Sen. Ted Cruz's Senate colleagues could get away with murdering the Texas senator on the Senate floor.

"The most dishonest person in America is a woman, who's about to be president," Graham said in remarks at the Washington Press Club Foundation's annual dinner in Washington, a reference to Hillary Clinton.

"How can that be? My party has gone bats--- crazy," he said to a room full of members of Congress and the media.

Graham ended his long-shot bid for president in December, but has remained a vocal critic of Donald Trump and Cruz.

"If you kill Ted Cruz on the floor of the Senate, and the trial was in the Senate, nobody could convict you," he said of Cruz, who is not well-liked by many of his Senate colleagues.

House Minority Leader Nancy Pelosi also delivered a few lines at Cruz's expense, joking that it would be fun to spend time with the Canadian-born senator at a Justin Bieber concert or Maple syrup tasting.

Graham also made a few jokes at his own expense, saying the room was the largest crowd he's addressed "during a Republican debate."

After riffing on his failed campaign and his endorsement of Jeb Bush -- who dropped out last week -- Graham donned one of Trump's "Make America Great Again" trucker hats and "endorsed" the New York businessman, with the hope that his campaign would meet a similar fate.
