Trump tapping several who served in first administration for National Security Council roles

President-elect Donald Trump is filling out his National Security Council with several officials who served in his first administration. 

Brian McCormack, a longtime energy consultant, and Andrew Peek, a seasoned Middle East adviser, will take senior roles on Trump's White House National Security Council, according to people familiar with the matter, signaling a focus on Iran and on beefing up domestic energy production. 

The National Security Council is an advisory body made up of regional and subject-matter experts who help coordinate domestic and foreign policy.
