I watched a good deal of the hearing and although John Dean was getting most of the press, I was impressed with the two female attorneys who also testified, Barbara McQuade and Joyce White Vance.
Dean: "Remarkable parallels" between Mueller report and Watergate Dean; McGahn should testify before Congress Barbara McQuade: The president was "threatened" by the special counsel exposing more potential crimes over the course of the investigation which compelled him to want to fire Mueller from the probe. Joyce White Vance called lack of obstruction charge into question.
Repubs on the committee tried several times to say this hearing was a waste of time - John Dean replied the hearing is important because it informs the public, given most Americans along with many in Congress did not read the Mueller report.
