I believe the democrats on the committee made sure these protesters were there and sitting right behind Sec. Rumsfield so they would be centered in the camera. Have to get that sound bite for the evening news, don't you know?

Shows again how off-course the RATS are... this will strengthen American resolve for the president's position, not diminish it.
Perhaps unbelievably, RATS still do not, cannot accept a post-9/11 America.
