Isaac Aguigui, the Army private and alleged ringleader of a plot to assassinate Barack Obama and "take over" Ft. Stewart in Georgia, apparently served as a page at the 2008 Republican National Convention in Minnesota. That's his mug shot after he was arrested for the alleged murder of Pvt. Michael Roark on the left. At right is a 2008 Reuters photo with the caption: "Republican National Convention page Isaac Aguigui watches from the edge of the floor at the start of the first session of the 2008 Republican National Convention in St. Paul, Minnesota September 1, 2008."
