Cross a list of Obama donors with a list of federal employees and we get a list of possible willing accomplices. This didn't have to come as a order through the chain of command, Obama already had a list of people who he may be able to turn with a small nudge, some visits to the White House, etc.
White House is more political than democratic!
I'd like to see a list of Republican donors nationwide who contributed more than $5000 since 2008 and have someone contact them all to see if they've been audited or had any unusual IRS interactions or harassment since 2009. My guess is it's 60-80% in the affirmative.
