During a campaign rally on Saturday in New Hampshire, Donald Trump moments ago called for drug tests ahead of the third presidential debate, comparing himself and Clinton to athletes.

"I think she's actually getting pumped up, you want to know the truth. She's getting pumped up you understand. In fact, we're gonna be talking about that in a few minutes. She's getting pumped up for Wednesday night."

"We're like athletes right. Athletes, they make them take a drug test, right. I think we should take a drug test prior to the debate. Why don't we do that? We should take a drug test, prior, because I don't know what's going on with her, but at the beginning of her last debate, she was all pumped up at the beginning, and at the end it was like, 'Oh, take me down,' " Trump said, imitating Clinton.

"She could barely reach her car, so I think we should take a drug test'"

Trump said he was willing to take drug test. The GOP nominee often raises questions about whether Clinton has the stamina and strength to serve as president.
