Late Show host Stephen Colbert criticized President Trump’s remarks claiming that he would have run into the Parkland school to stop Nikolas Cruz, the 19-year-old gunman who killed 17 people.

“O.K. There’s a lot in there that I doubt, but the part I really don’t believe is that he can run,” Colbert quipped on his program.

He also remarked about Trump’s checkered past in avoiding the draft: “Look, sir, we already know how you react to combat situations. You got five deferments from Vietnam. What are you gonna do, run in there and stab ’em with your bone spurs?”
