He helped engineer one of the greatest upsets in political history-the election of Donald J. Trump as president of the United States. Now, after a short and turbulent tenure in the White House, Steve Bannon is working on the outside to propel forward his populist agenda even when it puts him at odds with the Trump administration. Unafraid to speak the truth and unwilling to back down, Bannon has made headlines in recent months for slamming the Trump administration's approach to North Korea and China, backing controversial Senate candidate Roy Moore at all costs, and calling members of Trump's circle-including Trump's son Don Jr. and his son-in-law Jared Kushner-"treasonous" for meeting with Russians during the election.

What is Steve Bannon trying to achieve? Is he a political genius with a promising ideology, or a muckraker without allegiances?

In Bannon: Always the Rebel, veteran White House reporter Keith Koffler sits down for hours of interviews with Steve Bannon and gets the embattled former White House advisor talking about his plans, his current thinking about the Trump White House, and the reasons he's still fighting.

"Keith Koffler's book will help you understand why Steve Bannon still matters, and why he is one of the most powerful and important men outside the Oval Office." -SEBASTIAN GORKA, Ph.D., former deputy assistant to President Trump, author of Defeating Jihad, and chief strategist of the Make America Great Again Coalition.
