I've seen this referenced in several places. It's basically an article that says "we don't know what Mueller will find, but we know some things he's probably looking at." Here's a little favor:

Sater tried making it as a stockbroker, but his career came to an abrupt end in 1991, after he stabbed a Wall Street foe in the face with a broken margarita glass during a bar fight, opening wounds that required 110 stitches. (Years later, in a deposition, Trump downplayed the incident, insisting that Sater “got into a barroom fight, which a lot of people do.”)
