Whether they squirm, take the fifth, Nunes (Gowdy, etc) “tears them a new one”, and so on and so on....
Congress is not a law enforcement body. Nunes is not a prosecutor. No one involved in these farcical hearings can convene a Grand Jury, indict the guilty, prosecute them in a courtroom, or send them to prison.
Congressional hearings on matters like this are meaningless. It’s all about getting headlines and campaign sound bites.
The FBI and the DOJ are under the congress’ control , When a congressional committee requests documents from he FBI&DOJ etc. they are required by law to respond in kind . Congressional committees can expose laws violated within govt. agencies and influence a grand jury to charge and prosecute such violations . Nunes is simply doing a great job now by putting the FBI/DOJ on notice that stone walling will not be tolerated any longer .
