Interesting debate going on now on the Senate floor between Sen. Warner (R-VA) and Sen. Durbin (D-IL) about the influence of Iran on the ground in Iraq and congressional power to regulate the military affairs on the ground in Iraq. Sen. Warner is currently sponsoring a resolution that will "update" the president's power to act in military affairs in Iraq. Warner seems very skeptical of effects of Levin-Reed withdrawal amendment on the ground and says that he cannot support it.
