"I saw that as an absolute distraction - I think this president has been terrific at throwing up smoke screens and distractions - and that's exactly what I thought that was", said Sidlow.
"Following a routine morning threat briefing, Mr. Comey spoke to me and my chief of staff".
Sen. Mark Warner, D., Va., asked the attorney general if he had confidence in former FBI Director Robert Mueller's appointment as special counsel to probe whether the Trump campaign colluded with Russian Federation.
