President Barack Obama Thursday night authorized air strikes on the terrorist group which has been gaining territory in Iraq.
While Durbin, a Democrat, says he is glad the action involves no boots on the ground, he's still cautious about getting involved in the conflict.
"I understand the president's motivations. I don't quarrel with what he's concluded. I don't believe the American people or I have any appetite for sending more American troops into war in the Middle East."
Separately, Senator Kirk, a Republican, issued a press release saying that limited air strikes are the right move to weaken the Islamic State and to help religious minorities targeted by the group.
The Islamic State has strengthened and grown throughout Iraq and Syria, taking more cities as it advances.
Last summer, Kirk supported air strikes in Syria in response to President Bashar al-Assad's regime. Durbin did not. It's unclear if U.S. involvement in Syria would have prevented the growth of the Islamic State.
