Kevin O’Leary is being sued for defamation by a group fighting the construction of a data center in Utah after the “Shark Tank” star appeared on Fox News and claimed that some of the people involved with the opposition have ties to China, according to The Hill.

The lawsuit, which was also against Fox News, was filed Wednesday in Utah federal district court by Alliance for a Better Utah, Elevate Strategies, Gabrielle Finlayson and Josh Kanter. It claimed Kanter and Finlayson “suffered devastating damage to their reputations, significant financial losses, severe emotional distress, and ongoing threats to their physical safety” after O’Leary “attacked” them during their appearance on Fox News.

“Fox was instrumental in O’Leary’s smear campaign, putting him on air to attack plaintiffs five times in three weeks,” the lawsuit reads. “Despite O’Leary’s inherently unreliable claims and its clear lack of support for them, Fox repeatedly invited O’Leary onto its shows and allowed him to broadcast his false accusations to millions of viewers without any qualification.”

In late June, Fox News issued a statement apologizing for O’Leary’s claims. The statement read: “Kevin O’Leary appeared as a guest on the show on May 24 and discussed the ongoing controversy surrounding his planned data center project in Utah. He made certain claims related to opponents of his project. Mr. O’Leary has now corrected the record and explained that he has ‘no evidence’ that the Alliance for a Better Utah, Josh Kantor or Taylor Knuth are funded by China or the Chinese Communist Party.”

O’Leary issued his own statement on social media, retracting the allegations. He wrote: “I have recently appeared on several news programs and would like to clarify that I have no evidence that Alliance for a Better Utah, Elevate Strategies, Gabrielle Finlayson, Taylor Knuth or Josh Kanter are funded by China or the Chinese Communist Party.”
