PORTSMOUTH, New Hampshire  -- Donald Trump said today a drug test should be performed on the two candidates before the third and final presidential debate, implying that his Democratic rival Hillary Clinton may be on drugs.

"I think we should take a drug test prior to the debate. I do," Trump said at a midday rally at a car dealership. "We should take a drug test prior -- 'cause 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.' She could barely reach her car."

This comes in a slew of new personal attacks that Trump has unveiled against Clinton, including saying he wasn't "impressed" when she stood in front of him during the last debate.
