I agree with those that say the narrow focus of Russia has turned into the broad brush of over-reach, and it shouldn't have ever been allowed to.
Clinton argued the same thing, that Whitewater ended up as Lewinsky, and he had a logical argument about the broad brush, too.
Still, since the topic is Giuliani says Trump paid $130G to Cohen for 'expenses' over several months , I'd say Trump knew, the Feds now know that Trump knew, and Rudy is out there, putting it out now so it won't come out as a bombshell later.
Whether one is AT or NT or ST (sometimes Trump), isn't really the topic at hand here.
