Once more Stephen Colbert steps up to the challenge of educating President Trump about an issue he has clearly misunderstood.

As Colbert explains, Trump is all wrong when he tells credulous supporters that football players are kneeling during the national anthem in protest against the flag. “Those players are protesting against racial injustice, they’re not protesting the American flag. Saying that kneeling is a protest against the flag is like saying Gandhi’s hunger strikes were a protest against snacking.”

The Late Show host also offers a few pro tips for Trump on respecting the American flag (hint: don’t hug it!). He does a killer impression of weirdo Treasury Secretary Steve Mnuchin. And he offers a clue as to why NASCAR owners probably don’t have to worry about drivers protesting police misconduct.
