There’s no contest. Barney Frank and the Democrats set up Fannie and Freddie in such a way that the problems would be compounded, but whoever was running the agency at the time would make out like a bandit; think Franklin Raines. Newt got paid for the work he did, which according to the written contract, did NOT include lobbying. So Newt is not part of the Fannie and Freddie problem; that lies with Barney and his fellow Democrats, and the RINOs who enabled them to pass legislation creating the problem.
I think Jamie Gorelick was in there up to her eyeballs.
