Again..tactic is..threaten subpoena in order to get person on the record in interview
Sorry, but I think everyone is DEAD WRONG on this, if they dig deep and force this crook to testify, it will Seriously Implicate a substantial number of high pollutant politicians from BOTH sides of the Aisle.
Remember the Republican Leadership hates Trump as much as the Democrats do, they teamed up to defeat Trump. He is the real threat.
