Don't be surprised if "Deepthroat" has some data stored away for safekeeping.
Interesting what Hillary and Mr. Felt have/had in common ... total access to LOTS of FBI files
There is nothing to the timing except the Vanity Fair article which has been in the works and what looks like a good 3 or so years of Felt's name bubbling to the surface.
I believe this timing of this story is Hillary's. She knew the Senate race would center on presidential impeachment since Cox will be her opponent. CNN will air now watergate thoroughly, trash Nixon over again, and discredit Cox for the Senate race.
This is why the story is out at this time IMO.
