Cindy Sheehan Arrested Moments Before State of the Union

Peace activist Cindy Sheehan was arrested Tuesday in the House gallery after refusing to cover up a T-shirt bearing an anti-war slogan before President Bush's State of the Union address.

According to a blog post on Michael Moore's Web site attributed to Sheehan, the T-shirt said, "2,245 Dead. How many more?" -- a reference to the number of U.S. troops killed in Iraq. She was asked to cover it up in order to stay for the speech, but she refused.

House rules bar demonstrations in the galleries.
