CHICAGO (AP) — Jon Stewart has been on the sidelines for one of the wildest campaign seasons in memory. But he's weighing in with a new dig at old foe Donald Trump, labeling the presumptive Republican presidential nominee a "man-baby."

The comments came in a Monday taping of a podcast with President Barack Obama's former aide, David Axelrod, at the University of Chicago.

Stewart joked that Trump has the "physical countenance of a man and a baby's temperament and hands," adding that as a "man-baby," he isn't sure Trump is eligible to run for president.

The former "Daily Show" host also took a swipe at likely Democratic nominee Hillary Clinton, describing her as "a very bright woman without the courage of her convictions."

Stewart left the Comedy Central program in August.
