A lot of comments and conjecture at this Market Watch link. Page 8 has a detailed list of current and past people involved. I was surprised to see both Rahm Emanuel and Newt Gingrich on the list.
Hillbilly Bill appointed Rahmbo to Freddie Mac in 2000. Also obama would not release any board meeting notes etc. In regards to Rahm’s participation in Freddie Mac. I believe I read this in the Chicago Tribune in March of 009.
