Donald Trump rallies have been a bit scary as of late, as protesters and supporters clash over the controversial Republican presidential front-runner. Still, Stephen Colbert, the host of CBS’ “The Late Show,” found a way to get a few laughs out of the situation.

The violence at Trump rallies has been dominating the news cycle for over a week, but on Tuesday, Colbert took aim at one incident in particular: Trump’s claim that a protestor who rushed the stage at a rally in Ohio on Saturday had ties to terrorism. 

"The protester was charged with disorderly conduct and inducing panic, which means he could be the next Republican front-runner," joked Colbert.

The comedian went on to criticize Trump for claiming on Twitter that the protester was connected to the Islamic State group, also known as ISIS, and linking to a doctored video that featured Arabic music and showed the protester dragging the American flag on the ground. 

"With that beard like that, he is either in ISIS or Mumford and Sons," Colbert chided, pointing out the protester's facial hair. 

Colbert's biggest shot came after the comedian played a video of Trump defending his tweet on CNN by saying that all he knows is "what he sees on the internet." 

"I want to let that sink in for a second," said Colbert, astonished. "Trump is America's gullible uncle, just forwarding whatever he sees online. Obviously his first state dinner will be honoring that imprisoned Nigerian prince," referencing the prevalent internet scam. The segment ended with a video of Colbert's making: a cat in a turban set to Arabic music. Colbert mocked Trump, accusing the cat of having ties to terrorism. 

Trump scored key wins Tuesday in the GOP primaries in Florida, Illinois, and North Carolina. Ohio Gov. John Kasich, though, pulled off a big victory in his home state, preventing a Trump sweep that would have almost certainly guaranteed the real estate mogul the Republican nomination. However, Trump still holds a commanding lead in the delegates, with 621. Texas Sen. Ted Cruz is a distant second with 396 delegates, followed by Kasich with 138 delegates. Florida Sen. Marco Rubio dropped out of the race on Tuesday after losing his home state.
