Seen what? She made a plea deal. I'm not a lawyer nor do I play one online, but my understanding of a plea deal with a prosecutor is that the guilty will testify for said prosecutor. In this case, Fan Willis as prosecutor, Sydney Powell is the guilty person.
I fail to see why someone would leap to the conclusion that the plea deal between Willis and Powell applies to cases in other states or at the Federal level.
What will probably happen is that Smith will use their guilty pleas against them in his case. At this point they can seek to make a plea deal with him, plead the Fifth or go to trial.
