Ron Paul's super PAC is secretly funded by San Francisco gay billionaire Peter Thiel, the San Francisco Chronicle reported.

Thiel, who co-founded PayPal and invested early in Facebook, has given $2.6 million to Endorse Liberty, the super PAC which has released several ads attacking Paul rivals Rick Santorum, Newt Gingrich and Rick Perry, without ever meeting Paul.

The German-born Thiel is a 44-year-old conservative Christian who has previously supported gay rights causes and artificial intelligence research.

“He has great insight,” Jimmy LaSalvia, the executive director of gay GOP group GOProud, told the paper. “He also is inquisitive, and most of the conversations I've had with him have been him asking questions. He gathers a lot of information.”

Thiel, who currently helms Clarion Capital, a global hedge fund, has provided more than half of Endorse Liberty's proceeds.

“I think Peter has a gift for seeing trends,” said Endorse Liberty founder Jeffrey Harmon. “PayPal and Peter's early investment in Facebook are examples of the vision. I believe Peter can see that Ron Paul is the future of the Republican Party.”

Others interviewed by the paper disagreed with Harmon's assessment of Thiel.

“You're only a genius if people don't know about your bad bets,” said Wade Randlett, a fundraiser for President Barack Obama's re-election campaign, who noted Thiel has lost a “gigantic” amount of money in his own hedge fund.

Paul has previously denied any knowledge of racist and homophobic writings in the newsletters he published in the 1980s and 90s.
