Donald Trump on Saturday said he and Hillary Clinton should both take drug tests before the next presidential debate, suggesting without evidence that Clinton was under the influence of drugs during the last debate.

“We’re like athletes,” Trump said in New Hampshire, speaking at a campaign event billed as a speech on ending the opioid epidemic.

“Athletes—they make them take a drug test, right? I think we should take a drug test prior to the debate,” he said. “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 he would be willing to take a drug test.

Ironically, his statement comes just weeks after many viewers questioned Trump’s frequent sniffling during the first debate. Those viewers included former presidential hopeful Howard Dean, who issued a tweet questioning if Trump had used cocaine.

It must be noted that here is nothing to substantiate Dean’s hypothesis. In fact, as the Washington Post pointed out, Trump claims he doesn’t even drink alcohol.

Trump, meanwhile has spent months raising doubts about Clinton’s health and stamina. Her campaign has maintained that she is healthy and, in turn, has questioned the legitimacy of reports on Trump’s health.

The third and final presidential debate will take place on Wednesday.
