The US Attorney for the District of Columbia, Ronald C. Machen - the man responsible for the aggressive surveillance and phone record scrutiny at Fox News - is also a big donor to the Obama Campaigns. At the time of his appointment, the Washington Post wrote a profile on Machen including this tidbit:
Over the years, he has donated $4,350 to Obama's campaigns. He gave $250 to Obama's U.S. Senate campaign in 2003, a year before Obama, then an Illinois state senator, emerged on the nation's political radar, according to campaign finance records.
Furthermore, in June of 2012, Sen. John Cornyn (R-TX) questioned Attorney General Eric Holder about the appointment of Mr. Machen to head-up the leaks investigation. During the questioning Sen. Cornyn revealed that not only was Machen a donor to the Obama campaign, he was also a volunteer for Obama for America. Cornyn called into question whether he could conduct the leaks investigation in a fair and non-partisan way.
