The Biden plan will also "Immediately restore the White House National Security Council Directorate for Global Health Security and Biodefense, originally established by the Obama-Biden administration." That National Security Council group was eliminated by Trump in yet another stable genius move. Trump doesn't need experts with experience when he thinks that his intuition is always right.
It was moved, not eliminated.
Reading is fundamental. "That
National Security Council group was eliminated"; I wrote that because that
National Security Council group was indeed eliminated. There is no more
National Security Council Directorate for Global Health Security and Biodefense.
https://www.whitehouse.gov/nsc/"The National Security Council (NSC) is the President's principal forum for considering national security and foreign policy matters with his senior national security advisors and cabinet officials. The NSC is chaired by the President. Its regular attendees (both statutory and non-statutory) are the Vice President, the Secretary of State, the Secretary of the Treasury, the Secretary of Defense, and the Assistant to the President for National Security Affairs. The Chairman of the Joint Chiefs of Staff is the statutory military advisor to the Council, and the Director of National Intelligence is the intelligence advisor. The Chief of Staff to the President, Counsel to the President, and the Legal Advisor to the NSC are invited to attend any NSC meeting. The Attorney General and the Director of the Office of Management and Budget are invited to attend meetings pertaining to their responsibilities. The heads of other executive departments and agencies, as well as other senior officials, are invited to attend meetings of the NSC when appropriate."
In short, having a seat and a voice at The National Security Council matters, quite a lot in fact.
Not having a seat at the National Security Council table matters; it amounts to a reduction in that security priority and reduces direct access to the President.
