When a catastrophic explosion wipes out the entire United States government during the State of the Union address, low-ranking cabinet member Tom Kirkman is thrust into the Oval Office. This high-stakes premise forms the core of Designated Survivor, a political drama and thriller that ran for three seasons across ABC and Netflix. Behind the gripping conspiracies and frantic crisis management is an expansive ensemble of politicians, staffers, intelligence agents, and family members. Understanding who these characters are and how their loyalties shift provides a clearer lens on the series' sprawling geopolitical and domestic conflicts.
The designated survivor premise turns everyday bureaucracy into a tense survival test. While Tom Kirkman navigates his unexpected presidency, a web of allies and adversaries tries to shape, support, or sabotage his administration. From dedicated Secret Service agents to ruthless political operatives, the cast of Designated Survivor delivers a rotating mix of idealism and cynicism. This character guide breaks down the major players, their arcs, and their impact on Kirkman’s turbulent tenure.
The Presidency and the Inner Circle
At the center of the political storm stands Tom Kirkman, joined by a small group of loyal advisers who try to keep the country from fracturing completely.
Tom Kirkman
Portrayed by Kiefer Sutherland, Tom Kirkman is the Secretary of Housing and Urban Development who becomes the President of the United States by constitutional default. An academic and architect by trade rather than a seasoned politician, Kirkman starts out as an outsider plagued by self-doubt. Yet, his moral clarity, sharp intellect, and refusal to play dirty politics define his presidency. Over three seasons, he transitions from an accidental leader to a fiercely independent politician willing to risk re-election for his principles.

Aaron Shore
Played by Adan Canto, Aaron Shore serves as Kirkman's Chief of Staff and later as National Security Advisor. Originally a close associate of the previous administration, Aaron is sharp, ambitious, and intensely loyal. His background allows him to handle the grueling political maneuvering of Washington while keeping his personal ethics intact. Aaron's journey involves navigating complex romantic entanglements and probing questions about his family's heritage, all while remaining one of Kirkman's most dependable pillars.
Emily Rhodes
Portrayed by Italia Ricci, Emily Rhodes is among Kirkman's earliest supporters. Starting as a special adviser, she eventually rises to Chief of Staff. Emily is fiercely intelligent and deeply committed to the Kirkman agenda, but her ambition occasionally clouds her judgment. Her character arc explores burnout, ethical compromises, and a crisis of faith in the political system, leading to a complex relationship with power and administration secrets.
Seth Wright
Played by Kal Penn, Seth Wright is the White House Press Secretary who stays with Kirkman from the very beginning. Seth brings a grounding, cynical realism to the West Wing, serving as the bridge between an panicked public and a beleaguered administration. His quick wit and media savvy make him a fan favorite, while his personal storylines touch on representation, identity, and the heavy toll of defending political decisions under constant scrutiny.
Law Enforcement and Intelligence
Outside the West Wing, a parallel narrative unfolds in the shadows, focusing on the hunt for the conspirators behind the Capitol bombing.
Hannah Wells
Portrayed by Maggie Q, FBI agent Hannah Wells is the driving investigative force of the series' first two seasons. Relentless, highly trained, and often operating outside the boundaries of protocol, Hannah uncovers the vast conspiracy that brought Kirkman to power. Her pursuit of the truth takes her across international borders, placing her in constant peril as she exposes corrupt actors within the government and military.
Damian Rennett
Played by Ben Lawson, Damian Rennett is an MI6 intelligence officer embedded in Washington. Working alongside Hannah Wells, Damian brings a layer of international espionage to the domestic investigation. Their dynamic mixes professional tension with mutual respect, though Damian's hidden agendas and secretive ties keep both the characters and the audience guessing about where his true loyalties lie.
The First Family
The personal toll of the presidency is heavy, weighing heavily on Kirkman's immediate family as they adjust to life in the public eye.
Alex Kirkman
Portrayed by Natascha McElhone, Alex Kirkman is Tom's wife and a high-powered immigration attorney. Unlike her husband, Alex is comfortable with the rough-and-tumble nature of Washington politics and frequently pushes him to be bolder and more decisive. Her legal background and fierce protective instincts make her an invaluable confidante, though her independent advocacy often creates political vulnerabilities.
Leo Kirkman
Played by Tanner Buchanan, Leo is the Kirkman's teenage son. His storyline primarily deals with the typical pressures of adolescence magnified a thousandfold by the presidency, including paparazzi, security details, and questions surrounding his biological paternity that surface during the first season.
Key Political Adversaries and Allies
Governance requires cooperation with lawmakers and officials who often have competing visions for the country.
Cornelius Moss
Portrayed by Geoff Pierson, Cornelius Moss is a former president and a towering figure in the political establishment. Initially brought in as an elder statesman and Secretary of State to lend credibility to Kirkman's administration, Moss represents the old guard of Washington politics. His relationship with Kirkman shifts from mentorship to bitter rivalry as personal ambition and differing governance philosophies collide.
Lorraine Zimmer
Played by Julie White, Lorraine Zimmer enters the picture during the Netflix-produced third season as Kirkman's campaign manager. Brash, unfiltered, and entirely focused on winning, Lorraine represents the modern, data-driven, and often cutthroat reality of contemporary political campaigns. Her methods frequently shock the idealistic members of the West Wing, injecting friction into the administration's re-election bid.
Behind the Casting: How the Ensemble Came Together
The casting process for Designated Survivor leaned heavily on established television veterans. Kiefer Sutherland brought immediate gravity to the lead role, capitalizing on his action-thriller pedigree from 24 while adopting a much softer, more intellectual demeanor for Tom Kirkman. Meanwhile, Maggie Q brought martial arts training and a background in procedural dramas to her role as Hannah Wells, anchoring the physical action sequences that balanced the dialogue-heavy political scenes.
The series underwent several showrunner changes during its run, transitioning from ABC's broadcast network format—which favored standalone crises wrapped up in 43 minutes—to Netflix's serialized storytelling, which allowed for deeper character flaws and darker political themes. This shift directly impacted the cast dynamics, letting characters like Aaron Shore and Emily Rhodes explore morally gray territory that standard network television rarely permitted.
