White House chief strategist Steve Bannon has been removed from his seat on the National Security Council, reversing one of the most controversial decisions of the young Trump administration.

A filing on Tuesday in the Federal Register did not list Bannon as a regular attendee of NSC "principals committee" meetings, as he previously was. The change adds Director of National Intelligence Dan Coats and Chairman of the Joint Chiefs of Staff, Marine Corps Gen. Joseph Dunford, back to the committee. It also adds Energy Secretary Rick Perry, who controls the nation's nuclear arsenal.

Despite the move, Bannon retained his security clearance, NBC said.

Bloomberg first reported the news Wednesday.

In late January, Bannon was given a full seat in a move that downgraded the roles of the chairman of the Joint Chiefs and the director of national intelligence. It is highly unusual to give a political advisor a seat on the committee.
