“You should never let any Muslims in this country,” Clinton said, characterizing Trump’s idea for a “temporary” ban on allowing Muslims into the United States as a permanent one. “That’s a dumb, dumb, dumb idea.”

Clinton also mentioned Trump’s plan to build a wall between the United States and Mexico and get Mexico to pay for it.

“I don’t think you could get Mexico to pay for it, but you could put it up,” he allowed.
