Oh, and this.
Sater is one of those lesser-known names to watch for. He is deeply and centrally involved in, well, anything he’s involved in. A very big fish, with extensive knowledge of his …ahem… “business”. If he’s truly cooperating now (and that’s still unclear but more promising than before), that means the investigation could likely spread to dozens of new high-to-top-level targets. If Sater completely flips and is proactively cooperative, they’re going to need to build a new prison. The Feds will likely try to cut a deal with him, as they have before – if he gets charged with something minimal like lying to investigators, there’s your sign.
