Evidence Withheld, Media Silent

If a Republican administration had done this, the Media would be screaming so loud you wouldn't be able to sleep at night. Good thing a Democrat did it, so we can all sleep better...

From the Washington Free Beacon article, "State Department Office Removed Benghazi Files After Congressional Subpoena":

State Department officials removed files from the secretary’s office related to the Benghazi attack in Libya and transferred them to another department after receiving a congressional subpoena last spring, delaying the release of the records to Congress for over a year. 

Attorneys for the State Department said the electronic folders, which contain hundreds of documents related to the Benghazi attack and Libya, were belatedly rediscovered at the end of last year.

...The delay has had consequences. The Benghazi Committee had already completed the majority of its interviews with diplomats and government officials regarding the Benghazi attack before it received the latest tranche of documents. 

Let's look at the timeline on this:

1. February, 2013: Hillary Clinton left her post as secretary of state.
2. March, 2015: "The House Benghazi Committee requested documents from the secretary’s office in a subpoena..."
3. April, 2015: The files were "retired" to the Bureau of Administration, Office of Information Programs and Services (that is a long name, so let's just call it "BOPS").  

Admittedly, it is possible this was done as a CYA move by former aides to Hillary. Or it could have been ordered by President Obama. But I doubt we will ever know, since journalists are too stupid to know even when Trumpsters are pranking them...
