Part one of the series examines the earliest days of the Russian Federation investigation, the FBI's investigation into Hillary Clinton's emails and their impact on Election Night 2016, when Donald Trump stunned the world and was elected president.
It will air over two nights on September 27 and 28, more than a month before the November 3 general election.
The Comey Principle co-stars Holly Hunter as former Acting Attorney General Sally Yates, Michael Kelly as former FBI Director Andrew McCabe, Jennifer Ehle as Patrice Comey, Kingsley Ben-Adir as both President Obama and Peter Coyote as Robert Mueller.
The second part is "a virtual day-by-day account of the tempestuous relationship between Comey and Trump and the intense and chaotic first months of the Trump presidency".
This series picks up as Trump was sworn into power in the 2016 election and the aftermath which followed.
While the preview clip keeps Gleeson's Trump mostly hidden in the shadows, the actor can be seen wearing prosthetics and sporting the President's trademark tan.
"I know some people in the bureau have it out for me - but I'm the President now", Gleeson rasps in an eerily Trump-like timbre in the trailer. Comey was sacked by President Trump in 2017 after controversy over the FBI's investigation of the Hilary Clinton emails scandal and the separate investigation into Russian affect in the United States election.
In accordance with Self-importance Truthful, The Comey Rule portrays the president as "vulgar, corrupt, and deeply indebted to the manipulations of Vladimir Putin". Steve Zissis, Shawn Doyle, Brian d'Arcy James, Dalmar Abuzeid William Sadler, Richard Thomas, T.R. Knight, Joe Lo Truglio, Spencer Garrett, Michael Hyatt, Damon Gupton and Seann Gallagher also star. From that unforgetable photo of Trump whispering in Comey's ear during their handshake photo to the infamous dinner where Trump allegedly asked Comey for his loyalty, this series promises to dig up all the political dirty laundry we saw aired on the nightly news back in 2017.
