Gen. Jack Keane (Ret.), Fox News military analyst, on the investigation into the crash of the U.S.S. McCain.

Hours after the guided-missile destroyer the USS John S. McCain collided with an oil tanker, speculation abounds that the vessel may have been the target of a cyberattack.

Admiral John Richardson, chief of Naval Operations, says right now the Navy has no indication that an intentional action was the cause. Nevertheless, he added, “We are looking at every possibility and leaving nothing to chance.”

Meanwhile, the U.S. Navy’s top officer has called for a one-day operational pause. The top brass is ordering a comprehensive review of training and operations in its Pacific fleet after two collisions in three months.
