A four-hour miniseries that will air over two nights, “Divided States of America,” will focus on the polarized nation that the next president will inherit. The “Frontline” production bows Jan. 17-18, 2017, on PBS, days before the 45th president will be sworn in.

The show offers “an in-depth view of the partisanship that gridlocked Washington and charged the 2016 presidential campaign, the rise of populist anger on both sides of the aisle and the racial tensions that have erupted throughout the country,” PBS says in its announcement.

“Drawing on extensive new interviews with White House and congressional insiders from both parties, as well as ‘Frontline’s’ vast body of reporting on the Obama era, ‘Divided States’ digs into the causes of America’s intense polarization and questions how the next president and Congress can govern in an era of complex challenges,” PBS announced. “This television event, led by veteran ‘Frontline’ filmmaker Michael Kirk and his team, tells a revealing story that’s not just about Barack Obama’s presidency, but about America itself.”

Said Kirk: “When America elected its first black president eight years ago, many thought we were entering a new and hopeful era. But now, from race to guns to the economy, we’re living in a deeply polarized moment — in American politics and American life. This film explores why we’ve reached this point, how Washington has reacted to the upheaval that is fast defining our times and what it means as we look to the tenure of the next president.”
