U.S. National Security Advisor H.R. McMaster said today that available information indicates that the incidents at U.S. airports were merely a communications failure, while affirming that the possibility of a cyberattack has not been ruled out.
McMaster told reporters at the White House that efforts are underway to resolve the communications issue and that there is no cause for alarm, urging Americans not to fear or worry about their relatives who are traveling.
He noted that the current priority is to restore communications, land all aircraft, and then return to normal operations.
