Comey is the Head of the FBI. Not the CIA, DNI or any of the other Alphabet Soup agencies.
If the warrant for a intercept was applied for on the basis of Foreign Agents, Comey wouldn’t have been in the loop.
Or this is a ploy to smoke out the black hats.
Comey Denies, meanwhile the Obama people are busy trying to destroy evidence. Meanwhile, Comey, Sessions and Trump sit back and check last weeks records with what gets deleted this week and by who. Maybe even a few FBI wiretaps themselves have been applied for and granted to find out who Sally Yates, Lynch, Holder, Clinton, VJ and Obama are calling right now to get things cleaned up.
Actually, the FBI is responsible for counterintelligence so they should be in the middle of it.
