AP: Manafort Offered to Help Putin Gov't in 2005

This is going to shake things up quite a bit, making Trump's very bad week even worse. The AP has uncovered a $10M/year contract dating back to 2005, between a close Putin ally and Paul Manafort. Manafort offered up a proposal to influence the US government in order to create favorable conditions for Russia:

"We are now of the belief that this model can greatly benefit the Putin Government if employed at the correct levels with the appropriate commitment to success."

Manafort is in a lot of trouble as he never registered as a foreign agent, and that's a felony. But what if he hid that money from the IRS? That would provide the FBI with a lot of leverage to get Manafort to spill the beans on all sorts of activities further up the chain.
