Cohen's wording makes it sound like he was an "active and eager participant" in golden showers. I hate to kink shame, but Ew.
Much like with Bolton, I refuse to pick a side between two equally morally reprehensible people (and to the extent that Cohen is betraying at least some attorney/client confidences he's obviously not a hero). For what it's worth, however, a lot of these allegations are things that we already have a lot of evidence of.
We know that Trump Org. stated radically different values for its assets when dealing with creditors versus when it dealt with the IRS. We obviously know about the catch and kill arrangement with the Enquirer and the NDAs. The "deals with corrupt officials from the former Soviet Union" could relate to either the Trump Tower Moscow project or the property in Baku. I'm not sure anything has been built in Baku in the last three decades without deals with corrupt officials from the former Soviet Union.
