Why would anyone be asked to sign an NDA(non disclosure agreement) for simply serving at a US mission? Unless you were engaged in illegal or unfavorable (to say the least) activities, what reason would there be to ask those who survived the attack to be quiet? At least we know now why we haven’t heard from the other survivors, the regime told them to shut up, making them sign their life away!
Get on your Congressmen to demand a select committee and public hearings on Benghazi. The regime is banking on Americans short memory to just move along and bury what happened last year getting 4 Americans killed. This is what they do on every issue, make promises to get answers to just drag things out until the next story hits to distract you.
