As the US readies for one of the most consequential midterm elections in recent history, the third season of the groundbreaking political documentary series The Circus, produced by Left/Right, returns with nine new episodes starting on Sunday, September 16 at 8 p.m. ET/PT on SHOWTIME in the US.

The Circus is produced by Left/Right, a Red Arrow Studios company, for SHOWTIME. John Heilemann, Mark McKinnon, Alex Wagner, Banks Tarver and Ken Druckerman serve as executive producers.

Hosted by John Heilemann, Mark McKinnon and Alex Wagner, The Circus launched the first part of its third season this past spring recording the series’ biggest premiere week ever, growing 10 percent in its second week and delivering a series high of 1.3 million viewers, topping its election week total in 2016.

This fall, The Circus will return to its roots. The show will hit the campaign trail for the midterm elections, which will not only determine control of Congress but how the Trump presidency will play out. The series will continue to cover the impact of the administration’s policies as well as the legal and political controversies swirling around the White House. The Circus will follow multiple individual stories and key characters from the campaigns, and capture their unique perspectives in weekly half-hour shows. With intimate, behind-the-scenes access, cameras will offer viewers a look at what the public rarely sees and explore the high human drama of American politics.

The spring episodes of The Circus featured Heilemann, McKinnon and Wagner reporting from Moscow, St. Petersburg, London and Washington as they covered the ongoing drama around President Trump and all things Russia. Subsequent episodes took a deep dive into the unfolding developments in Special Counsel Robert Mueller’s investigation, the Stormy Daniels lawsuit and the criminal probe of President Trump’s former personal lawyer Michael Cohen.
