This is hysterical — today the Onion has been perpetrating a running gag about members of Congress holding some visiting schoolchildren hostage. They started with tweets about gunfire heard in the capitol building, then ran this article —
Shaken witnesses reported that the ordeal broke out around 10 a.m. this morning, when in the midst of a Capitol building tour, Sen. Harry Reid (D-NV) suddenly burst into the National Statuary Hall with a pair of black panty hose over his head and began firing a Beretta 9 mm handgun into the air, shouting, “Everybody down! Everybody get the fuck down!”
Apparently the tweets caused some panic.
Somewhere in satirists heaven, Orson Welles is laughing his ass off.
