Rumsfeld: Washington has not indicated mission in Syria

Former Secretary of Defense Donald Rumsfeld weighs in on Syria on CNBC's "The Kudlow Report."

"I think that what's lacking in all of this is the administration has simply not indicated what the mission will be," he said. "Until you do that, you can't explain to Congress what your goal is. Until you do that, you can't fashion a coalition of other countries to be supported."
