Sen. John McCain, R-Ariz., suggested that national security adviser Susan Rice isn’t taking the Boko Haram kidnapping of hundreds Nigerian girls seriously enough after Rice said that the United States would only advise rescue operations.

“If she believes that the seriousness of hundreds of young women being kidnapped doesn’t argue for the United States to make every effort to rescue them, than she and I just have a sharp difference of opinion,” McCain told the Washington Examiner. “It is a human rights violations we’re dealing with: the kidnapping and possible sale of these girls. And I guarantee you, Ronald Reagan, if he could have rescued them, would have rescued them.”
