Since Saturday's shooting in Tucson, Sarah Palin has found herself at the center of the ongoing debate about violent rhetoric in politics. On Wednesday, Palin released an eight-minute video in response. In the video, Palin condemns the shootings while stressing the importance of America's First Amendment freedoms. Palin also defends her use of a map with cross hairs targeting swing districts around the country, including Rep. Giffords', accusing journalists and pundits of "blood libel." For more on the video, host Robert Siegel speaks with Karen Tumulty, national political reporter for The Washington Post.
