Umm. That was before the immunity ruling.

Why would that matter? None of those cases involved any criminal liability for the President. And the President's been immune from civil liability for acts taken in office for decades now.

Ya' mean Sec of Defense Michael Flynn?

Great argument. Thanks for playing.

And everyone below him. As pointed out by Dope1, every single person who would be involved in abducting and imprisoning Donald Trump (in this scenario) on the orders of Joe Biden would be at risk of a lifetime in prison for violating countless criminal and military codes.

Plus, I don't think Flynn is seriously in the running for SecDef. He didn't even make the short list when Trump was riffing on potential appointments:

....and there's no benefit to Trump to naming him. Plenty of other people that he could pick - including Pompeo - that would be ardent supporters and team players without getting his transition team wrapped around the axle in an extremely tough confirmation battle.
