A new report 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, recently spent $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.
Koch and companies he controls have also given $3 million to Restore Our Future, the main super PAC working to elect Mitt Romney.
