I’m deeply grateful for Secretary Mattis’s years of service to the United States of America. Secretary Mattis’s resignation letter powerfully raises concerns from members of both parties about the President’s haphazard, impulsive approach to security issues, his failure to strategically confront our adversaries, his contempt for our allies, and his desire to abandon America’s vital role in maintaining an international order that protects our security and our values.

Members of both parties must step up now to do everything we can to promote a coherent American foreign policy that will keep us safe, secure, and free.
