The Early Warning Blog has a copy of a letter recently sent to Defense Secretary Rumsfeld by Republican Senator John Warner , Chairman of the Senate Armed Services Committee. The letter asks Rumsfeld to "conduct a thorough review of the entire legal framework governing
a President's power to use the regular armed forces to restore public order" .

There is also information on a military exercise today of Granite Shadow -- described as a plan for "emergency military operations in the United States without civilian supervision or control".
