Donald Trump has repeatedly called for a ban on Muslims entering the U.S. until "we figure out what is going on," saying it again after the Orlando massacre. On Tuesday, late-show host Stephen Colbert tried to do the presumptive GOP presidential nominee a favor and figure it out himself.

On CBS’ "The Late Show with Stephen Colbert" Tuesday, the comedian mocked Trump's response to the massacre at the Orlando dance club Pulse early Sunday. The deadly act of terrorism is the worst mass shooting in American history, leaving 49 people dead and more than 50 people wounded. In the aftermath of the shooting, Donald Trump gave a speech renewing his call for a Muslim immigration ban, chastising President Obama and presumptive Democratic nominee Hillary Clinton for not using the term "radical Islamic terrorism" and suggesting that the president perhaps sympathized with the shooter.

“This whole speech, with its nativism, its fear-mongering and, especially, its self-aggrandizing in the face of tragedy, feels like a new low,” Colbert said. “It makes me long for the days when Trump was just bragging about the size of his penis.”

The comedian then played a clip of Trump appearing on Fox News Monday, where the real estate mogul suggested that perhaps the president sympathized with the Orlando shooting.

“Look, we’re led by a man that either is not tough, not smart or he’s got something else in mind,” Trump said. “And the something else in mind — you know, people can’t believe it. People cannot. They cannot believe that President Obama is acting the way he acts and can’t even mention the words ‘radical Islamic terrorism.’ There’s something going on. It’s inconceivable. There’s something going on.”

Colbert took Trump at his word and pulled out a chalkboard to try to figure out "what was going on" after all. The blackboard was covered in many of the buzzwords Trump uses in his speeches, including "Obama," "Muslim," "Something Going On" and "Radical Islam." Sarcastically trying to connect the dots, Colbert drew lines between the terms, resulting in a swastika.

"No, no, no, no, no, no, that can’t be it,” Colbert said, erasing the Nazi symbol. “There’s got to be a simpler answer.”
