Partisan divisions emerge over U.S. mission in Iraq

Top-ranking Democrats who appeared on political talk shows Sunday advocated for a limited mission and insisted that the Iraqi government must respond to the growing threat of the extreme militant group ISIS, which calls itself the Islamic State but formerly was known as the Islamic State in Iraq and Syria.
