sits down with robert mueller, that that should be sort of a precedent for any interview in the future. it's also interesting, shep, again he went back to the idea of no collusion, no crime, and therefore why should there be an interview. which, again, when you look at the evolution of that, the president saying yes and yeah and today. i don't see any reason why there should be an interview. it sounds like he's a little less eager to sit down with the special counsel now than he was when he was first asked about it no more than six months ago. >> shepard: makes since, john bussey, if you misstate a fact, to be nice, if you misstate a fact and you're not under oath, that's one of the things he could ask for, not being recorded, it's one thing. if you're under oath, it's pretty obviously perjury. then that's impeachable. >> yeah. there's that, and i think probably no matter what happens, the rulemaking before going into the room. it's the president talking to the fbi.
