FILES - In Michael Wolff's book (Fire and Fury: Inside the Trump White House), former President Steve Bannon's adviser brutally attacks Donald Trump and his entourage. The book, which was due to be released on January 9, was brought forward to Friday, January 5 after the U. S. President tried to prevent its release. The latter denounced Thursday evening in a tweet a content 'full of lies'. ------- National Security Advisor Michael Flynn and Senior Counselor to the President Steve Bannon, sit nearby as President Donald Trump speaks on the phone with Prime Minister of Australia, Malcolm Turnbull in the Oval Office on January 28, 2017 in Washington, DC, The call was one of five calls with foreign leaders scheduled for Saturday. Bannon was CEO of the Trump campaign. The White House now says Bannon will sit on the National Security Council -- a place usually insulated from politics. Even before gaining a seat on the NSC, Bannon was already one of the most powerful people in the White House. It's a breathtaking rise for someone whose job before joining the Trump campaign was CEO of Breitbart News, an ultra-conservative and highly controversial website.
