A day before Alexandria Ocasio-Cortez was sworn in as the youngest-ever US congresswoman, a Twitter user tried to embarrass her with footage of her dancing in college.

The video shows Ocasio-Cortez and fellow Boston University students dancing to a segment of Lisztomania by Phoenix.

"Here is America's favorite commie know-it-all acting like the clueless nitwit she is," read the tweet from @AnonymousQ1776, who incorrectly said it was from her high school days. The account and the post have both since been deleted.

It was a clip pulled from a longer video posted to YouTube in 2010 and inspired by the library dance scene from the 1985 movie The Breakfast Club. Ocasio-Cortez's moves mirror those of Ally Sheedy.

If the tweet was an attempt to humiliate Ocasio-Cortez, it failed. Many people, including an array of celebrities, tweeted their support.

Well, @AOC is officially done. She’ll never recover from the world seeing her...

"She'll never recover from the world seeing her... (watches video) ...dancing adorably and having fun with her friends in high school?" wrote comedian Patton Oswalt.

Oscar winner Russell Crowe said "she's fantastic," while Star Trek's George Takei tweeted that he wants dance lessons from her.

It even won support from some Breakfast Club cast members, with Sheedy tweeting  "I LOVE THIS," and Molly Ringwald telling Ocasio-Cortez that she's "in the club."

Ocasio-Cortez tweeted a video response on Friday, revealing that she's still dancing to the tune of Edwin Star's 1970 song War.

"I hear the GOP thinks women dancing are scandalous. Wait till they find out Congresswomen dance too! Have a great weekend everyone," she wrote with the video.

Wait till they find out Congresswomen dance too!
