The U.S. is not quite sure yet how to deal with the worsening conflict in Iraq, and has not yet replied to Iraq's formal request for U.S. air power to take on the militant group known as the Islamic State of Iraq and the Levant.
U.S. President Barack Obama has been mulling over how to deal with the crisis, as the rebels have taken control of more territory in recent days, as well as Iraq's main oil refinery.
On Wednesday, he told top Congressional leaders that he does not need permission from lawmakers for any action in Iraq.
"The president's been watching and we've been watching for over a year as a situation in Iraq continue to be undermined and yet nothing, nothing has been done to reverse it."
Also on Wednesday at a Senate hearing, chairman of the Joint Chiefs of Staff General Martin Dempsey, explained the difficulties of launching an attack from the air.
The top general, who has extensive experience commanding Iraqi troops, also expressed doubts that the U.S. has enough intelligence right now on potential targets considering how quickly things have escalated in Iraq.
Earlier this week, the U.S. deployed an aircraft carrier and missile ships in the Persian Gulf, leaving open the possibility of manned air or drone strikes on the Sunni militants.
