No, but it was, and continues to be, a federal crime to lie to FBI agents. She did so. End of story.
If she would have just shut up she would not be in this position. She came forward with information that turned out to be a lie. If anything she should have been charged for giving a false report.
There are lots of federal crimes. Tell me, is it worse to lie under questioning, or worse to lie in a courtroom under oath? I'm genuinely curious about how many people have gone to jail for claiming to be innocent of an offence that was never even formally charged. And didn't the prosecution in a related case engage in a bit of lying, about the very evidence MS is going to jail for. (I admit the details of this escape me.)
All federal agents.
