But it was an exchange on Donald Trump that provided O'Reilly's most surprising comment. The Fox News commentator conceded that the presumptive Republican nominee patted himself on the back in his response to Omar Mateen’s assault at Pulse nightclub that left 49 dead and 53 wounded.
Hours after the shooting, Trump wrote on social media that he appreciated the congratulations for "being right on radical Islamic terrorism."
At Colbert's suggestion that Trump's response was "self-congratulatory," O'Reilly responded, "Yes, it is. He's a politician. It shouldn't shock you."
Applause erupted when Colbert pointed out that it's grandstanding.
"He wants to be president," O'Reilly said. "He's using this terrorism issue to bolster his popularity."
"So he's making a political tool out of a terror attack," Colbert said.
Said O'Reilly: "That's what he's doing."
