An ad produced by the Joe Biden presidential campaign has landed itself a defamation lawsuit after smearing embattled teen Kyle Rittenhouse as a "white supremacist."

On Wednesday, Rittenhouse's lawyer Lin Wood went after Biden over the ad published earlier in the day on Twitter, captioned, "There's no other way to put it: the President of the United States refused to disavow white supremacists on the debate stage last night."

Meanwhile, the campaign ad, seen over 2.4 million times as of writing, flashes an image of Rittenhouse among various images and a clip from Tuesday night's debate.

"In addition to suing Facebook for being falsely accused of being mass murderer, Kyle Rittenhouse has defamation claim against Joe Biden for falsely accusing him of being white supremacist & militia member responsible for violence in Kenosha," Wood announced via Twitter.

"Candidate Biden = Defendant Biden," he added.
