With New Book On Political Divisiveness, Former Gop Official Rings An 'Alarm Bell'

Peter Wehner served in three Republican White Houses. Now, he's written a book about the current state of national political discourse. In “The Death of Politics,” Wehner analyzes the tone and rhetoric used by President Trump, and how it’s fraying the American republic. Wehner sits down with Judy Woodruff to discuss tribalism, evangelical Christians and why his work is still a “book of hope.”
