mcgahn was a strong witness for the president's case and the strategy is working. his thinking behind this is that if mueller's team gets all of these answers from all of the people around the president and 1.4 million documents, then he has no need to question the president, right? and he would have no legal basis on which to argue it up through the supreme court to question the president. do you agree with john dowd that this was the right strategy to just let mcgahn go and assert no attorney-client privilege? >> no, i don't agree with it. i'll come back to sort of the pros and cons of that, but i think it's very dangerous not to assert the privilege and it's important for us all to remember, there are two kinds of privilege at stake here. there's the so-called executive privilege, which got litigated in water gatd and then there's the more traditional attorney-client privilege with a twist, which is mcgahn is the white house counsel not trump's person lawyer. he's really a government lawyer.
