Donald Trump, running neck-and-neck for the GOP presidential front-runner position with Ben Carson, joined the attack on his rival on Sunday, accusing the retired neurosurgeon of "pathological disease" over the disputed stories in his biography.
"He writes a book where he went after his mother, hit her on the head or wanting to hit her on the head with a hammer, hitting a friend in the face with a padlock, hard in the face," Trump said Sunday on
"Meet the Press."
Trump sounded doubtful of Carson's story that he attempted to stab a friend at age 14, only to be thwarted by a belt buckle.
"If you know belt buckles, they turn and they twist," he said. "I don't think they could have stopped a knife with the force of a strong man."
Trump continued his attack on Carson for having "pathological disease." On Friday's
"O'Reilly Factor," Trump suggested Carson need to "take pills."
"If you have pathological disease, that's a problem," Trump said on "Meet the Press. "He wrote it, I didn't write it. He's going to have to explain a lot of things away."
The then ticked off a list of other stories being questioned by the media: a West Point scholarship offered at a dinner with Gen. William Westmoreland and the Egyptian pyramids being built by Joseph to store grain.
Host Chuck Todd said Trump had "done a political trick" by referencing every negative Carson story and asked if that's because he's a political threat.
"I think everyone's a threat to me," Trump responded.
