Hedge fund manager Paul Singer will bankroll a super PAC for Republican candidates who support gay marriage.

Singer told The New York Times' Frank Bruni that he will provide an initial $1 million for the American Unity PAC.

The single objective of the PAC will be “to encourage Republican candidates to support same-sex marriage,” Bruni wrote.

“There's a feeling among some people that the Republican Party is harsh on some things,” Singer said, referring to the party's stances on abortion, birth control, immigration and gay rights.

On gay marriage, he added: “Atmospherically and tonally, it's part of the landscape of so-called harshness.”

Singer, who is straight but has a gay son who married his husband in Massachusetts, the first state to legalize such unions, is considered among the most important Republican donors nationwide. He has given nearly $10 million of his own money toward efforts to legalize gay marriage in New York, New Hampshire and New Jersey.

The PAC would alleviate the concerns of some Congressional Republicans “who could be on the verge of support” but worry about becoming the target of anti-gay marriage groups, Singer said.

In earlier remarks, Singer suggested Mitt Romney's anti-gay rhetoric was all talk.

“I don't think it's going to be a harsh environment [for gay rights] in a Romney administration,” the 67-year-old Singer said. “It's a process if Mitt Romney is elected – it's a process of pressure, education.”
