DOJ Deputy Director Rod Rosenstein, Special Counsel Mueller, and new FBI Director Ray are all currently guilty of Obstruction and Refusing to Comply with a Congressional subpoena by refusing to turn over documents / data.
During Questioning in front of Congress today FBI agent Strzok informed Congress that the FBI ordered him not to answer questions about the Mueller investigation.
STRZOK: FBI COUNSEL HAS INSTRUCTED ME NOT TO ANSWER QUESTIONS ABOUT MUELLER PROBE
The question of Strzok's proven bias covers his participation in Special Counsel Mueller's Witch Hunt...prior to his being fired after his bias was publicly exposed.
So questioning regarding his actions in the Mueller probe were definitely appropriate; however, he refused to answer, explaining he had been directed not to comply / answer Congress' questions.
(The Mueller Witch Hunt sounds a lot like Obama's promised but failed-to-be-delivered Administration: 'Most Transparent Evuh')
So, one of the 3 co-conspirators already proven to be Obstructing Justice and violating a Congressional Subpoena did so again by telling Strzok not to answer certain questions under oath before Congress.
Surprise, surprise....
Strzok: FBI Counsel Has Instructed Me Not to Answer Questions About Mueller Probe
The Republicans in Congress yesterday just proved that they are guilty of attempted obstruction of justice and interference in a federal investigation.
Those are actual crimes.
