After four days of near silence on the Tucson shootings, Sarah Palin stirred controversy yesterday when, in a videotaped speech posted online, she used the term "blood libel" to fire back at critics in the media.  She says they are unfairly trying to draw a connection between her campaign rhetoric and the deadly shooting spree. "Blood libel" is the centuries-old myth that Jews use Christian blood in rituals.

A few hours after Palin's internet video debuted, President Obama exhorted Americans to stop partisan bickering. We sort out what it all means with Washington Post White House reporter Peter Wallsten.
