While riding an Amtrak train Thursday, a former NSA director discovered his off-the-record comments to reporters were being Tweeted out by a nearby passenger.

Michael Hayden was talking on his phone, unaware that a fellow passenger was overhearing everything, and began live Tweeting the details. Hayden eventually figured out who was doing all the Tweeting.

Being a good sport about the whole thing, he sat down to take a picture with the passenger.
