was trying to sell about wikileaks and the stuff that russian military intelligence stole from the democrats and the clinton campaign for that witness tampering charge, does it matter in legal terms whether a message -- whether the witness tampering message is sent in private or whether that message is broadcast to millions of people over twitter does that legally make a difference to prosecutors? can you tamper with witnesses really, really, really out loud? joining us now is barbara mcquade, former u.s. attorney in michigan barbara, thank you so much for being here. >> oh, thanks for having me, rachel. >> i see a tonal relationship between the witness tampering messages that mr. stone was charged for today and the sorts of things that the president has said in public about michael cohen. does it matter whether these things are said publicly or in private? >> no, it really doesn't the law doesn't say so i mean, other than the fact that they both clearly watch too many gangster movies, there's a lot in common between the statements that roger stone is making and that president trump is making
