During last weekend’s “Pride” event in Chicago over the weekend, the city’s Mayor Lori Lightfoot went on a bizarre profanity-filled rant against U.S. Supreme Court Justice Clarence Thomas, a conservative. She screamed at the crowd, “F**k Clarence Thomas!”

Fox News reports:

The [D]emocrat took to [T]witter Monday evening to defend her use of profanity after the video of her at the Pride event went viral. Lightfoot tweeted a picture of herself at the event pointing to a person in the audience wearing a T-shirt that read “F— Clarence Thomas.” Lightfoot simply captioned the picture, “I said what I said.”

The mayor of the third-largest city in the country was speaking on stage at the city’s Pride Fest. She began by saying, “If you read Clarence Thomas’ concurrence.” Someone then yells at the mayor from the audience to which she replies, “Thank you. F— Clarence Thomas. He thinks that we are going to stand idly by while they take our rights – our right to marry – our right to have children – our right to live.”

Lightfoot, Chicago’s first openly gay mayor, was enraged at Justice Thomas for suggesting that last week’s landmark decision overturning Roe v. Wade should be a prelude to overturning gay marriage.

The backlash to Lightfoot’s attack on Justice Thomas was swift. Multiple mayoral challengers came out to express their disgust.
