"I'm proud of what the Breitbart team has accomplished in so short a period of time in building out a world-class news platform", Bannon said in a statement cited by Breitbart News.
Former White House strategist Steve Bannon's remarks critical of President Donald Trump's administration appear to be costing him dearly.

A Breitbart employee, who spoke on the condition of anonymity because they were not authorized to discuss the matter, told CNN that "everyone seems stunned". A veteran of the U.S. Navy, Bannon has worked as an investment banker and dabbled in the film industry.
Former White House chief strategist Stephen Bannon, in the book, described Donald Trump's son-in-law Jared Kushner's meeting with a Russian lawyer as "treasonous" and "unpatriotic".

"Bannon died of his own sword", said Roger Stone, a long-time Trump friend. Sirius said in a statement its programming agreement was with Breitbart, not with Bannon.
