Rep. Alexandria Ocasio-Cortez (D-NY) mocked White House Deputy Chief of Staff Stephen Miller, calling him a “clown” and encouraging her followers to “laugh” at what she described as the “insecure masculinity” of men in the Trump administration.

Speaking during an Instagram Live session, the progressive congresswoman told her 13 million followers that humor was a “powerful” weapon against what she called the “authoritarian tendencies” of the Trump White House.

“The point is that they are scraping and grasping at straws because they have nothing else,” Ocasio-Cortez said. “Laugh at them. Stephen Miller is a clown! I’ve never seen that guy in real life, but he looks like he’s, like, [4 feet, 10 inches tall]. He looks like he is angry about the fact that he’s [4 feet, 10 inches] and he’s taken that anger out on any other population possible. Like, laugh at them.”

She continued, “One of the most powerful cultural things you can do to a political movement that’s predicated on the puffery of insecure masculinity — that’s what this is about — is to make fun of them. One of the best ways to dismantle a movement of insecure men is by making fun of them.”

Ocasio-Cortez, who frequently uses livestreams to mix political commentary with personal interaction, said humor is more effective than outrage when confronting what she sees as extremism.
