legal team. who is advocating submit to the interview, and who has been advocating do not submit to the interview? >> generally speak, based in our reporting with carol leonnig, my colleague, we learned that ty cobb has been supportive of the idea of sitting down with mueller. he is a veteran washington lawyer. his perspective based on our reporting is one shared by the president. that if he sits down with mueller and his investigators, he will maybe be able to conclude this probe and bring it to a quicker end. but then john dowd, the president's recently departed russia attorney, he's also a veteran washington lawyer. he has worked and interacted with robert mueller for a long time. he has been telling the president do not put yourself at legal risk. you are a subject. remain a subject. if mueller wants to move forward, it's his decision not for you to have to answer questions sitting down in a room. >> lawyers like dowd and others have seen subjects move to targets as a result of doing these kinds of interviews.
