“I’m nervous. And I saw the headline today –- race tightening. Trump ahead in Ohio and Florida. If this race is even the week before the election, somebody is going to have to go out there," Maher said, while performing stand-up at the DAR Constitution Hall in Washington, D.C.

"Why do you think they let Hinckley out?”

Maher was referring to John Hinckley Jr., who shot former President Ronald Reagan in 1981.

On Saturday, Hinckley was released from a Washington psychiatric hospital.

A judge in July gave Hinckley "full-time convalescent leave" from the hospital, which will let him live with his mother in Virginia. But he will still be under restrictions, according to CNN.

Maher also reportedly make a joke about "Second Amendment people." He was referring to comments by the Republican nominee in which he appeared to joke about the possibility gun owners could take action against Clinton.

“Hillary wants to abolish, essentially abolish the Second Amendment,” Trump said speaking at a rally earlier this year.

“By the way, if she gets to pick her judges, nothing you can do folks,” he then added.

“Though the Second Amendment people, maybe there is, I don't know.”
