Back in May, "Shark Tank" star Kevin O'Leary made a series of media appearances accusing some vocal opponents of his data center plans in Box Elder County, Utah, of being foreign-backed agents.

Now, Mr. Wonderful is being sued for defamation.

"Recently I appeared on various 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," [OLeary] wrote in an Instagram post from June 25.
