Stephen Colbert slammed Donald Trump on Tuesday’s episode of The Late Show, drawing a swastika to explain the presumed Republican presidential nominee’s response to the Orlando, Florida mass shooting on Sunday.

In the wake of the attack, which left 49 dead and 53 injured, Trump gave a speech on national security, claiming the shooter, 29-year-old Omar Mateen, was “born in Afghan,” and that if elected, he “will suspend immigration from areas of the world where there’s a proven history of terrorism against the United States, Europe or our allies until we fully understand how to end these threats.” (Mateen was an American citizen, born in New York.) It’s the second time Trump has discussed banning Muslims from entering the United States, having previously revealed his plans last year after the terror attacks in Paris and San Bernardino, California.

“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 on Monday’s Late Show. “It makes me long for the days when Trump was just bragging about the size of his penis.”

In addition to his planned remarks, Trump appeared on Fox News to question President Barack Obama’s motives following the nightclub attack.

“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.”

In a separate radio interview, Trump also attacked Obama for not showing a “lot of anger” after the shooting, and said he would “let people figure it out” with regard to what that meant.

“Let the people figure it out. He’s just going to give you clues, like the $100,000 Pyramid,” Colbert joked. “Your clues are ‘Obama’ and ‘something going on,'” the host said, before adding, “What my racist aunt would say at a picnic.”

From there, Colbert decided to tie all of Trump’s Orlando and terrorism comments together using a chalkboard. The result was a swastika.

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

And there was, at least for Colbert: the next drawing was a circle with four lines running through it — a picture that Colbert joked “kind of looks like an a–hole.”
