Join us for a discussion of ALTER EGOS with New York Times correspondent and author Mark Landler and NBC News Chief Foreign Affairs Correspondent Andrea Mitchell.

In ALTER EGOS: Hillary Clinton, Barack Obama, and the Twilight Struggle Over American Power, Mark Landler takes us inside the fraught and fascinating relationship between Barack Obama and Hillary Clinton—a relationship that has framed the nation’s great debates over war and peace for the past eight years.

Spanning the arc of Obama’s two terms, Alter Egos goes beyond the speeches and press conferences to the Oval Office huddles and South Lawn strolls, where Obama and Clinton pressed their views. As Barack Obama prepares to relinquish the presidency, and Hillary Clinton makes perhaps her last bid for it, how both regard American power is a central question of our time.
