I’m re-posting my discussion of these issues here. We cannot criminalize conversations with foreign nationals about politics. That shoe doesn’t fit well on the other foot.
But we don’t know if Don Jr. made any deals in this meeting, accepted more than just information, or lied to investigators about any of these details. I’d be most concerned that Don Jr. lied to Congress in his long testimony, but it’s important to be clear and fair about what criminal law covers and what it doesn’t.
