dont forget...they are looking at the same type of activity from trump as well (like overvalued florida house sale to dmitry rybolovlev and lord knows what else directly through trump commercial properties).

if you want to make a case for collusion with a foreign government to a jury...its best to outline relationships with that foreign government where benefits could be sought in exchange for an end goal (ie - manafort joining trump campaign to 'get whole' with clients).

because one question everyone should be asking themselves:
with all of the shady foreign lobby work and money laundering that most people wanna keep in the dark...why was manafort so hellbent on getting such a high profile/attention gig on a major presidential campaign and offering to work for free? *wink wink*
