Congress divided over US military action in Iraq
Both Republicans and Democrats are split over whether the United States should use air power to assist Iraqi armed forces.
US lawmakers are deeply divided over whether to provide air support for the struggling Iraqi military in its fight against the Islamic State of Iraq and al-Sham (ISIS), blunting the pressure on the White House to move swiftly.
While a habitual group of vocal interventionists called for immediate action on June 12, many key lawmakers proved reluctant despite rapid gains by ISIS, an al-Qaeda spin-off.
President Barack Obama said June 12 that his national security team is "looking at all the options" but would not commit to any course of action.
Several Republicans urged military intervention following reports that Prime Minister Nouri al-Maliki has called for US strikes by drones and manned aircraft.
