Dan Pfeiffer was one of Barack Obama's first hires when he decided to run for president, and was at his side through two presidential campaigns and six years in the White House.
Using never-before-heard stories and behind-the-scenes anecdotes, Pfeiffer's book, "Yes We (Still) Can," examines how Obama succeeded despite Twitter trolls, Fox News (and their fake news), and a Republican Party that lost its collective mind.
Dan Pfeiffer is a co-host of the popular political podcast "Pod Save America."
