The Russia investigation is ongoing. As for the Stormy Daniels and another woman...it's not the act that's the issue, it's the cover up.
I don't know that there's been any cover up that would constitute anything illegal. Hypothetically, if Trump wanted to pay these two hurs himself to, A.) Keep getting his knob schlobbed a private matter and away from his hot wife, and/or, 2.) Keep them from going public during the campaign...then whatever. That's his business and strictly a moral issue. But, if his lawyer did in fact, take care of the $130K payment for the purpose of keeping Stormy quiet during the campaign, I think it can be argued that this is in violation of campaign finance laws. That would strictly be Cohen's problem.
You have two hurs here. One had no agreement (That I know of) to keep quiet. She sold her story about polishing the Trump Tower to The Enquirer for $150K. The CEO of said rag is tight with Trump so he sat on the story. Said Playboy hur got pissed and still went public and I believe also sued The Enquirer. Second pern hur played the Trump skin flute and the story to this point is that Cohen paid her off for a non-disclosure agreement, which she's completely ignored. Since the story is out, he ought to drag her ass to Court.
My opinion on what's going to come of it is they'll ultimately find that Cohen was falling on the sword for Trump, but The Donald was the one that financed the deal and just had Cohen draw up zee papers. If that's the case, then it's move along, nothing to see here.
