Just hours after federal officials arrested a man alleged to have plotted an actual attack on the Capitol, the U.S. Capitol Police  aren’t laughing about a joke tweet suggesting a similar siege.
The Onion, a satirical newspaper, wrote this on its Twitter feed Thursday morning:
The newspaper followed the “breaking news” tweet with a link to a satirical article  suggesting that House Speaker John A. Boehner (R-Ohio) is serving as spokesman for a “bipartisan group” of congressional hostage-takers. Subsequent messages appeared to provide real-time updates of the completely fictional situation.
The Capitol Police reacted angrily.
