Members of the Press Office for Foreign Affairs serve the President, the National Security Advisor and the White House Press Secretary on all press-related matters involving national security, defense and foreign policy issues. The NSC press secretaries maintain these principals' awareness of current foreign policy news items and coordinate all contacts between the NSC staff and the media.

The office's main responsibility is to represent the Administration's foreign policy to the press. It achieves this by coordinating the public messages of the U.S. government's diplomatic, defense and intelligence communities, by briefing the White House press corps on foreign policy matters and by responding to the requests and inquiries of foreign and domestic media.
