Republican presidential candidates are split on whether the U.S. should send ground troops to the Middle East to combat Islamic State militants.
And most of those who would commit troops offer few details on their plans.
Businessman Donald Trump says he's "OK" with sending ground forces, but doesn't say how many. He tells NBC he wants to cripple the Islamic State group by taking over their oil fields.
Carly Fiorina says the U.S. should offer aid in the fight. But she tells ABC's "This Week" that now is not the time for U.S. ground troops.
Former Ohio Gov. John Kasich tells CBS he would authorize ground forces only as part of an international coalition.
South Carolina Sen. Lindsey Graham stands alone with his call for 20,000 troops in Iraq and Syria.
