Answer:
The forum where the President and other executive branch members consider national security and foreign affairs issues is the National Security Council.
Step-by-step explanation:
The National Security Council is a body of the federal government of the United States that advises on external security. The council is chaired by the President, and plays a vital role in the elaboration and implementation of American foreign policy. The council is often associated with serious influence and with its usual meeting place, the Situation Room in the basement of the White House, which has been replicated in many Hollywood productions as a prototype of a modern boardroom.
