"C'mon! Mr. President, that's the one thing you're not supposed to say," Colbert said, smacking his forehead. "That's like going to an AA meeting and shouting, 'Who wants shots?'"
Trump also tweeted early Monday morning that the Justice Department "should have stayed with the original Travel Ban, not the watered down, politically correct version they submitted" to the Supreme Court.
"Mr. President, you can't criticize the Justice Department," Colbert said. "You control the Justice Department. To quote third-grade boys everywhere, 'Why are you hitting yourself? Quit hitting yourself.'"

"Mr. President, it's pronounced 'St. Petersburg,'" Colbert joked.
