President Trump was in his element Wednesday night, Seth Meyers said on Thursday's Late Night, as he whipped the crowd at his North Carolina rally into a "racist frenzy" by going after Rep. Ilhan Omar (D-Minn.).

Meyers said Trump has spent the last few days slandering Omar, who came to the U.S. as a Somali refugee and is a naturalized citizen, and stood by as the audience began chanting, "Send her back!" This was "one of the most vile spectacles in modern political history," Meyers declared, "a defining moment for our country, and any Republican who doesn't immediately condemn it should imagine how it will look in a history textbook years from now, because there will absolutely be a section on this and it will absolutely name everyone complicit in it and they will absolutely use the worst photo of you they can possibly find."

To prove it, Meyers put up a graphic showing a photo of Senate Majority Leader Mitch McConnell (R-Ky.) that made it appear as though his face was melting into a puddle of chins, and another of Sen. Lindsey Graham (R-S.C.) looking like a hissing bobcat out for revenge.
