Hahaha, I was going to post this!
I don't think it's real. The language and grammar use is very poor. It seems like it was written by someone who is not a native English speaker. I have a feeling the site was hacked, and a fake message was posted.
It was posted on the 12th, and it's still on their site. You would think that if their site was hacked, they would have realized it by now, seeing as they are the Department of Homeland Security.
