There is some confusion about Meadows "flipping."

Immunity is something else: This means essentially that he was forced to testify.

It works like this: If the DOJ gives use immunity, nothing he says can be used against him, so it's no longer possible to invoke the 5th Amendment.

(It's late so I'm not sure I explained it well.)

Ex-Chief of Staff Mark Meadows granted immunity, tells special counsel he warned Trump about 2020 claims: Sources

ABC News

A lot of people are assuming that "immunity" means Meadows is off the hook.

I also see some reputable legal commentators buying into the "Meadows flipped" narrative.

Immunity doesn't mean he can't be prosecuted. It means that anything he says after he was immunized can't be used against him.

It keeps people from hiding information by invoking the 5th.

If the prosecution learns something new from his testimony that implicates HIM, they can't use it.

Continued . . .

. . . but if they already had the info, they can use it, but they will have to show that they already had it.

To prevent this from being a problem they likely question him on a narrow topic that has nothing to do with his own criminal liability.

It is bad for Trump because obviously, they are forcing him to say something he doesn't want to say.

It is good for the DOJ because they get the info they want.

It is unlikely to be good for Meadows.

@Teri_Kanefield How much can a person resist a subpoena under immunity. If the prosecutor is pursuing a wide-ranging conspiracy-anything you do, legal or not, can be used to show you're part of it, so testifying to stuff related to the conspiracy is self incriminating (unless you're immune from the conspiracy charges altogether)
