Billionaires Provide 91% of Funds for Rove-Tied Attack Ads

In August, American Crossroads raised $2,639,052. Fully $2.4 million of that -- or 91 percent --  came in the form of gifts from just three billionaires.

Salon previously reported that the group is getting a staggering amount of support from billionaires, several of whom made their fortune in the energy industry and live in Texas. Last month Trevor Rees-Jones, president of Dallas-based Chief Oil and Gas, contributed another $1 million to American Crossroads, on top of the $1 million he gave earlier this year. Fellow billionaire Robert Rowling, CEO of the company TRT Holdings, also gave Crossroads his second $1 million donation in August.

Another key thing to note is that American Crossroads has a partner group, American Crossroads GPS, that is organized under a section of the tax code that does not require disclosure of donors (though it also imposes some spending restrictions). American Crossroads GPS is raising millions of dollars, the group told Politico, but we'll probably never know from whom.
