Stephen Colbert had some fun with the ongoing feud between President Trump and Sen. Bob Corker (R-TN).

The Late Show host echoed Corker’s remarks how Secretary of State Rex Tillerson, Secretary of Defense James Mattis, and Chief of Staff John Kelly separate “our country from chaos.”

“That’s right, he believes we’re in the before times,” Colbert quipped.

He then mentioned how Corker said “we could be heading towards World War III” because of Trump.

“All this time, we’ve been worried that the next war would be caused by artificial intelligence,” Colbert reacted. “Turns out the real danger is natural stupidity.”

Colbert then mocked Trump’s tweets attacking Corker, saying he was “made to sound a fool, and that’s what I am dealing with!”

“What you’re dealing with is a crippling case of narcissistic personality disorder,” he reacted.
