“@AOC , Congratulations on being the youngest woman ever being elected to Congress!” the band tweeted from their official account on Friday. “Tendrement, Phoenix.”

The tweet also featured a link to an old video of then-college student Ocasio-Cortez dancing with friends on a roof at Boston University that resurfaced a day before the congresswoman was sworn into office this week.

The video, which was filmed eight years ago, had re-emerged earlier this week in a tweet from the account @AnonymousQ1776, which has since been deleted, aiming to attack Ocasio-Cortez.

The tweet featured an edited clip of the video along with the caption: "Here is America's favorite commie know-it-all acting like the clueless nitwit she is.”

But the attempt to smear Ocasio-Cortez immediately backfired on social media as thousands of users, including freshman Rep.

Ocasio-Cortez also commented on the video's re-emergence in a statement to The Hill on Friday.

"It is not normal for elected officials to have a reputation for dancing well and I'm happy to be one," the New York Democrat said.

“I think it is just funny what is considered to be disqualifying. It is unsurprising to me that Republicans would think having fun should be disqualifying or illegal," she continued.
