Good morning, Washington. The National Air and Space Museum closed Saturday and at least one person was pepper-sprayed after hundreds of anti-war demonstrators tried to enter the museum to protest a drone exhibit. The group was carrying signs that are forbidden inside, and some individuals reportedly began shoving guards when asked to leave the signage at the door.

A group that may have been affiliated with Occupy D.C. or the Stop the Machine movement was maced while trying to protest at the Smithsonian National Air and Space Museum this afternoon. The museum is now closed.
