National Security Advisor Susan Rice panned Senate Republicans' suggestions that President Obama deploy a U.S. special forces team to rescue the Nigerian girls kidnapped by Boko Haram, saying that additional support would likely be "advisory" in nature.

Rice laughed in response to a question about Sen. John McCain, R-Ariz., who said that he would send in a U.S. team with or without the permission of the Nigerian government.

"I think that, frankly, in all likelihood, if we were to do more with respect to a Nigerian request, it would likely be an advisory capacity, which is what we're doing thus far and what we could potentially do more of if we had better info on where the girls are located," Rice told the Women's Foreign Policy Group when asked if she would rule out a raid by special operations forces.

"To the extent that they make requests of us or others to provide support, we're open to entertaining those. But obviously, as I said at the outset, the most important thing now is to locate the girls," Rice also said. "There is no point in sending in any kind of additional support if we don't know where they are, so that has to be the first order of business."

McCain also said his plan was contingent on knowing the location of the kidnapped girls. “If they knew where they were, I certainly would send in U.S. troops for a rescue," he told the Washington Examiner's Susan Ferrechio. "In a New York minute I would."
