Donald Trump has elevated chief strategist Steve Bannon to a top national security role, while downgrading the roles of the director of national intelligence and the chairman of the Joint Chiefs of Staff. The move adds Bannon to the “principals committee” of the National Security Council—a role usually filled by the secretaries of state and defense and senior intelligence officials. Bannon is the former head of right-wing Breitbart Media, a haven for the white nationalist movement.
