It will be extremely interesting if Comey testifies again under oath before Congress. He claims that Trump asked him to drop the investigation of Flynn although he did not report such “coercion” to his Justice Department superiors. He will of course be asked to explain. Far more interesting and telling will be his responses to questions if and how Obama and Lynch intervened and influenced his “decision” not to recommend the indictment of Hillary Clinton. Either he tells the truth or perjures himself. He cannot be sure that tapes or documentation exists regarding Obama/Lynch involvement. That is why, IMHO, Comey will not voluntarily testify again before Congress and all attempts to subpoena him will be opposed by Democrats and the MSM as a infringement on the special prosecutor’s investigation. He knows too much about Obama and Lynch.
Well unless he backs out, he has agreed to testify: http://www.cnbc.com/2017/05/19/comey-agrees-to-testify-in-open-before-senate-intelligence-committee.html
Do you seriously think that any congress critter is going to ask genuine probing questions of Comey? Congressional investigations are shams, frauds used for political purposes.
Congress is NOT a law enforcement body. It is a law making body (or used to be until it ceded most of its authority to the nameless, faceless, unelected bureaucracy). Congressional hearings are supposed to be for the purpose of oversight and to obtain information necessary to craft laws. They are not supposed to be for political witch hunts.
