The New York Times reported Friday that new emails being reviewed by the FBI potentially connected to the Clinton investigation were discovered during a separate investigation into Weiner, the estranged husband of longtime Clinton aide Huma Abedin.

Trump previously called Weiner a "sicko" in 2013, which he referenced during the rally Saturday.

"It's called good judgment. It's called good instincts," Trump said.

The GOP nominee also speculated on whether or not Abedin would continue to be part of the Clinton campaign.

"I wonder, is she gonna keep Huma?" Trump asked.

"Huma's been a problem. I wonder if Huma's going to stay there. And I hope they haven't given Huma immunity because it seemed that anybody that walked down the sidewalk got immunity," he continued.

"I hope they haven't given Huma immunity because she knows the real story. She knows what's going on."
