President Donald Trump reorganized his National Security Council on Wednesday, removing chief strategist Stephen Bannon from a key committee and restoring the roles of top intelligence and defense officials, according to a person familiar with the decision and a notice published in the Federal Register.

The realignment increases the influence of National Security Adviser H.R. McMaster, whose public stances were sometimes at odds with those of Bannon. In addition to gaining greater control over the NSC, McMaster will have the Homeland Security Council under his authority.
