Kid Rock called Oprah Winfrey a fraud after she endorsed the Pennsylvania Senate campaign of John Fetterman, a Republican.

Kid Rock said Oprah aided Dr. Oz with his career. She found him to be a great person after vetting him. She's against him now. Oprah is not a real person.

Despite her relationship with Oz, Winfrey is supporting Fetterman in the Senate race.

Oz was a health expert on "The Oprah Winfrey Show" before he got his own talk show. He had a show in January.

He is interested in serving in the Pennsylvania Senate.

According to Rachel Tripp, senior communications adviser for the Oz campaign, Doctor Oz loves Oprah and respects the fact that she has different politics. He thinks we need more balance in Washington.

A recent poll shows Oz leading Fetterman by a small margin in the Senate race in Pennsylvania.

After Tuesday's election, which party will control the Senate will be decided.
