Having spent the larger amount of two years digging through innocuous reports, FOIA documents, and media reports (mostly foreign), the Gowdy announcement today is more than a little bit disingenuous.
We’ve previously predicted, long before the select committee was announced, that the Benghazi investigation would amount to all hat and no cattle.
The reasoning is very simple:
Both sides of the UniParty were charged with intelligence oversight of the joint CIA/State Department operations in Libya (2011) and Syria (2012) through the Congressional Intelligence Gang-of-Eight.
At the time the “Intelligence Gang-of-Eight” was:

♦ Speaker – John Boehner, ♦ Minority Leader – Nancy Pelosi; ♦ House Permanent Select Committee on Intel Chairman – Mike Rogers, and his ♦ Democrat counterpart Charles Ruppersberger; ♦ Senate Minority Leader Mitch McConnell, and ♦ Senate Majority Leader Harry Reid; along with ♦ Senate Intel Chair Diane Feinstein and her ♦ Republican counterpart, Saxby Chambliss.

Together with Hillary Clinton and President Obama the “Gang-of-Eight” was duplicitous in everything that took place.  Therefore there is no independent motive for the Gowdy committee to find any responsibility – the entire investigation is for public appearances only.
Further evidence therein can be found in this latest press release.  Note the specific wording and the specific emphasis we provide: 
Washington, D.C. — Select Committee on Benghazi Chairman Trey Gowdy (SC-04) released the following statement after the committee today received from the State Department a production of more than 1,100 pages of records, including files stored on network folders used by senior employees within the Office of the Secretary, and emails from Cheryl Mills, Jake Sullivan, Huma Abedin, Susan Rice, and Patrick Kennedy:

“It is deplorable that it took over a year for these records to be produced to our committee, and that our Democrat colleagues never lifted a finger to help us get them. Shame on them and everyone else who has demanded this committee to give up before gathering all of the facts. This investigation is about a terrorist attack that killed four Americans, and it could have been completed a lot sooner if the administration had not delayed and delayed and delayed at every turn.

For example, the committee still does not have records we requested over a year ago, and we are still waiting for some witnesses to be made available for interviews. As soon as possible, we will release our report and interview transcripts so everyone can see the evidence for themselves, and I’m confident the value and fairness of our investigation will then be abundantly clear to everyone.”  

Today’s production is responsive to a request made by the Select Committee in November 2014, and subpoenas issued in March 2015 and August 2015, and includes work-related emails from the personal email accounts of Cheryl Mills, Jake Sullivan, and Huma Abedin, which the State Department has had since summer 2015.

Blah, blah, blah…
How nice.  production of documents for “files stored on network servers“.
It isn’t the state department network server files that would hold the pertinent data.  It’s the non-network server files, the private communication network, that would be of value; that’s where the real communication was taking place.

Carry on….
