Depends on what Secret Service does. I saw a video of Trump in front of Mar-a-Lago yesterday when he was talking to a crowd of supporters and the SS had their rifles out for clear view. Secret Service normally cannot leave a President (present or past).
Yes, it was good. Seth is a good interviewer. I knew somewhat about Clif's background but not as much as I learned in this interview. I was surprised that Clif gave it because he had said that he was too busy for interviews these days.
