It’s going to be fascinating to watch. Several possibilities:
1. He’s another Scooter Libby and the prosecutors are just going to move on now. I doubt this is the case. It would mean they couldn’t get a conviction on the crime they were out to prosecute, but they caught him in a lie during their interviews with him and got him for that. This happens all the time. People are stupid and don’t want to admit to anything embarrassing, so they tell white lies or shade the truth, and it comes back to bite them big-time. Here, I think Flynn had counsel throughout the process so maybe that’s not what happened here. (He may have tried to talk to the FBI alone, early on, thinking he could make this go away. Common error.)
2. He is making a deal with the prosecutors in exchange for his testimony against another subject or target of the investigation. This is also very common — a standard approach by the feds to such matters. It’s also the one that has Democrats hyperventilating.
3. The news report you link to makes it clear that someone with an agenda is leaking information. It’s probably not Fynn’s people because he looks like a snitch and I doubt he wants that. I guess some of the prosecutors just couldn’t contain themselves. If so, I have no respect for them. Lawyers have to keep secrets.
I can see it now. Trump is impeached or resigns, Pence pardons him, and Joe Biden is elected in 2020, despite millions of YouTube views of him being all over that woman who was the wife of an Obama appointee. Biden runs with Al Franken, who by then has converted to Christianity and has represented and been absolved by the Rev. Wright, Obama’s jettisoned pastor. The country moves forward.
