"They're pointing to a protester," Trump said, amid boos from the audience. "Honestly, if you don't point, nobody's even going to know he's here. Weak voice. Weak voice. Don't worry."
The protester appeared to wave a Communist Party flag before it was taken from him as a uniformed officer led the protester away.
"Boy, he's a young one," Trump said. "He's going back home to mommy. Oh is he in trouble. He's in trouble."
"And I'll bet his mommy voted for us, right," Trump said, as the audience erupted in laughter.
Trump's rallies have attracted many protesters in the past, including one in Concord, North Carolina where he made a quip about a protester's appearance.
"Get out of here," Trump said. "Looks like a nice little guy, actually. Go home to mommy. Bye. Go home to mommy. Tell her to tuck you in bed. Aw, he's such a nice guy."
