Rock singer Kid Rock has said that he supports equal marriage, and has spoken out to say that he was “fucking embarrassed to be a Republican”, because of some party policies.

Reports from last week of a lawsuit against a catering company suggested that Lady Gaga had turned down $1 million (£650,000), to perform at the Republican National Convention in August, which Kid Rock performed at.

In the interview with Rolling Stone, he said: “Athletes and musicians make astronomical amounts of money,” and said that, against party policy, he supports equal marriage, and abortion rights.

“People get paid $100 million (£65 million) to throw a baseball! Shouldn’t we all take less and pass some of that money onto others? Think about firefighters, teachers and policemen. We should celebrate people that are intellectually smart and trying to make this world a better place,” he continued.

Speaking of paperless ticketing, which he wants to introduce to his concerts, to avoid having the richest, or most influential people being the ones with access to the best seats, he said he was annoyed that GOP lawmakers had passed laws in several states banning the practice.

“That’s one of the times I’m fucking embarrassed to be a Republican,” he said. “It’s fucking Republican lawmakers passing those laws, you dumbasses. They already did it in New York and they’re trying to do it in Michigan. I’ve even called some of those guys to try and stop it.”

Last August’s GOP convention featured performances by Kid Rock, as well as Journey. Meat Loaf also performed at a rally for former Presidential hopeful Mitt Romney.

In the interview he said that he supported equal marriage rights, as well as abortion, but he refused to say answer the question of whether he would support Hillary Clinton in 2016 if she ran against Rick Santorum.

He said: “Jesus. I’m not letting you snake me into that. Nice try, though.”

Earlier this week, former US presidential hopeful Rick Santorum spoke out against the idea that the Republican Party might support equal marriage, and said it would be “suicidal” if it did.

Two Republican Senators have recently come out in support of equal marriage. Mark Kirk of Illinois became the second Republican Senator to come out in support of equal marriage last week, after Rob Portman, one of the original sponsors of the Defense of Marriage Act, who also recently offered his support to same-sex marriage after the revelation that his own son was gay.
