re: New Benghazi E-mail Akin to Discovery of Nixon Watergate Tapes

This new email should be a big deal (even if you believe that the entire Benghazi "story" is not) because Congress subpoenaed these kinds of records and the administration ". . . illegally [withheld] subpoenaed material" from Congress. Were it not for a judge ordering the release of this email as a result of a FOIA lawsuit, this email likely would have never seen the light of day. If the State Department cannot convince a federal judge that the email is covered by a FOIA exclusion, there is no (legal) reason the State Department should not have provided that same email to Congress, pursuant to a subpoena obligating them to turn it over and the President and Secretary Kerry's promise to "cooperate in any ways Congress wants."

If this email isn't a "big deal" and there is nothing left to uncover regarding Benghazi, why did the State Department fight the FOIA request? Why did they choose to (illegally) withhold it from Congress? The fact that they fought the release of this email logically tells us there is still more to this story that the administration does not want made public.
