"Like you, I see what I see. ... Something's going on but I just hope she gets well and gets back on the trail and we'll be seeing her at the debate."

Clinton had to leave a 9/11 memorial early on Sunday after she became "overheated." A video surfaced of the Democratic nominee appearing to stumble into a black van during her departure.

She then went back to her daughter's apartment and later returned to her home in Chappaqua, N.Y.

The Democratic nominee's campaign said late Sunday night it would cancel a trip to California starting Monday for fundraisers and an appearance on "Ellen."

Trump said Monday he thinks health is an issue now, and he plans to release some medical records soon.

"I took a physical and I'll be releasing when the numbers come in. Hopefully they're going to be good. I think they're going to be good. I feel great," the GOP nominee said.

"I'll be releasing very, very specific numbers."
