On November 14, 2012, Mitch McConnell (R-Ky.) wrote to Elizabeth King, the Pentagon’s congressional liaison, with a an unusually credulous query. “I am writing on behalf of a constituent who has contacted me regarding Guantanamo Bay prisoners receiving Post 9/11 GI Bill benefits,” McConnell wrote in a letter acquired by Danger Room. “I would appreciate your review and response to my constituent’s concerns.”And the origin of McConnell's concern that Guantanamo Bay prisoners are receiving G.I. Bill benefits? You guessed it: a satirical website called The Duffel Blog which is basically the military's version of The Onion. In other words, the "articles" posted on the website aren't real. They are what we call "jokes."
And no, it's not like McConnell would have needed to do any research to discover that the the source was a humor website: the constituent who wrote the original letter linked directly to the post in question.
As for how on Earth McConnell could possibly have been so dense to fall for such an obvious joke, I have no idea. But if you're the type of person who is looking for patterns, it's worth noting that Sen. Rand Paul—who recently expressed concern about defense nominee Chuck Hagel's links to a fictional terrorist group—is also from Kentucky. Maybe it's something in the water.
