“He’s one of the dumbest human beings I’ve ever seen,” Donald Trump said. Trump: Lindsey Graham a 'disgrace,' 'nut job,' 'one of the dumbest human beings'

Donald Trump on Wednesday blasted former presidential candidate Lindsey Graham for criticizing his electability and temperament to be president.

“I think Lindsey Graham is a disgrace, and I think you have one of the worst representatives of any representative in the United States, and I don’t think he should run,” Trump said about the South Carolina senator at a campaign event in front of the lawmaker's home-state crowd. “I don’t think he could run for dog catcher in this state and win again. I really don’t. Other than that, I think he’s wonderful.”


Earlier Wednesday, in an interview on Fox News, Graham said the Republican front-runner would make a “terrible commander in chief” and said the Republican Party would get “slaughtered” with him as the nominee.

“He’s one of the dumbest human beings I’ve ever seen,” Trump said.

Graham suspended his campaign in December but struggled to gain any traction in the crowded GOP field in early-state and national polls.

“He ends up at zero [percent]. Zero,” Trump said. “Here’s a guy running for the presidency — he’s at zero. He leaves in disgrace, in my opinion.”

Trump said he watched Graham speak on “America’s Newsroom” and ridiculed him for going “crazy” when the billionaire’s name was mentioned.

“I saw him on television this morning, and I think he lost it. He said 'Donald Trump, he’s' — he couldn’t even talk,” Trump said. “He was shaking. The hatred. They say, 'What do you think of Donald Trump? Well, waahhh.' He went crazy. The guy is a nut job.”

Graham endorsed former Florida Gov. Jeb Bush in January, calling him the best potential commander in chief in the field. Trump, however, maintained that he didn’t want Graham’s endorsement or anything to do with him, for that matter.

“His thinking,” Trump began. “He says, ‘I know so much.’ He knows about the military? I could push him over with a little thimble.”

Trump added that Graham would lead the U.S. into World War III and continued to deride Graham for his struggling campaign. “I think I’d crawl in a corner and I’d hide. I would just sort of put out a release: I’ve left the race,” Trump said, again referring to Graham's low poll numbers. “I wouldn’t even give a news conference. I’d be too embarrassed.”
