With an "investigation" going into Trump ties to Russia, Trump can't really fire Comey as the Dems and MSM would use that to call for Trumps impeachment. For Comey's part, the investigation is employment insurance. As is, the more Comey talks, the deeper he digs the hole and more likely it becomes he perjures himself, if he didn't already this past week.
Thus his remarks that the investigation is not over. Comey would help his case if he were to prove the case is based on inside moves, like McCain's delivery of a dossier or unsupported intel from DNC sources to prove an investigation. There is always step one.
As in "This investigation is based on (blah, blah, blah)"
Law enforcement does not go off half-cocked just because they feel like it. Exceptions like Fast & Furious are exceptions.
Better for Comey to hang himself than Trump say “You’re fired.”
This. There’s no way Trump can fire Comey right now, the MSM would be all over him. It would look too banana republic.
He just needs to be sure that he has people he trusts plastered to Comey.
Comey serves at the pleasure of the President. He can be easily removed. Consider Comey in Protective Custody....courtesy of the President.
