Update News: Kid Rock called Oprah Winfrey a “fr*ud” after the television icon endorsed See More

Oprah helped Dr. Oz with his career,” the outspoken conservative rocker tweeted Saturday in a post that was retweeted over 12,000 times. “I assume because she vetted him and found him to be a wonderful person. Now she is against him. Oprah is a fraud. -Kid Rock.”

Winfrey announced on Thursday that she was supporting Fetterman’s Senate campaign despite her long relationship with Oz.

Oz, a celebrity doctor, regularly appeared on Winfrey’s talk show as a guest before he launched “The Dr. Oz Show”.

“I said it was up to the citizens of Pennsylvania and, of course, but I will tell you all this, if I lived in Pennsylvania, I would have already cast my vote for John Fetterman for many reasons,” Winfrey said at a virtual get-out-the-vote event.

Fetterman’s campaign told Fox News Winfrey’s support for the Democrat over Oz “speaks volumes.”

“Oprah is widely regarded as the person who helped launch Dr. Oz’s career, and knows him well,” the campaign said.

Rachel Tripp, senior communications adviser for the Oz campaign, told Fox News: “Doctor Oz loves Oprah and respects the fact that they have different politics. He believes we need more balance and less extremism in Washington.”

Kid’s latest comments come just five months after he refused to apologize for a drunken rant in which he attacked Oprah and Joy Behar by name at a Tennessee bar.
