Joint Base Andrews is, among other things, the home base of Air Force One and one of Obama's most frequent golfing locations. It is one of the most active bases for U.S. Military in the country.

According to reports, there was a training exercise/drill that began at 9:00 am that this report interrupted, but base officials are saying that this is a real situation ongoing.

According to Stars and Stripes, the Pentagon has reported a 'barricade situation' on the third floor of the medical facility. Updated reports are also saying there have been no shots fired so far, no reported injuries.

Update:

Shaking my head:

So then how does the Pentagon report it to Stars and Stripes as a 'barricade situation'? And on a military base, someone freaks out that someone is carrying a 'long rifle'? Sigh, this is what our military has become?
