Help defend Warren against the Super PAC attacking her. Sign up to make calls for her.

Last week, we told you about America 360, a mysterious Super PAC that is being staffed by a former employee of Sen. Scott Brown’s (R-MA) campaign. America 360 is taking aim at Elizabeth Warren, and so far had not disclosed its major donors.

Now, numbers have just been released that show the PAC’s major donors. We now know that the America 360 Super PAC is being funded almost entirely by a Koch company, and that it’s targeting Elizabeth Warren, an opponent of oil subsidies that help enrich the Kochs.

Here’s the scoop from Adam Smith of Public Campaign:

AAi??new reportAi??filed with the Federal Election Commission (FEC) shows that a pro-Scott Brown super PAC is funded almost entirely by Oxbow Carbon, the company controlled by William Koch, the lesser-known brother of Charles and David Koch. The group, America 360,Ai??recently spentAi??$200,000 on mailers in the Massachusetts Senate race to benefit Sen. Brown.

Mr. Koch donated $500,000 to the group in September through his Oxbow Carbon LLC. Former top Goldman Sachs executive Muneer Satter and Boston real estate developer Paul Robert Marcus each donated $25,000.

Note that one of the other major donors to the Super PAC is the Goldman Sachs executive Muneer Satter. Warren isn’t just a foe of oil subsidies — she’s probably the top opponent of Big Banks running for a Senate seat in November. That’s why nearly half of her opponent Scott Brown’s campaign funds are coming from the financial industry.
