Pulitzer winner Carol Leonnig exposes the Secret Service's alarming failures through interviews with 180 insiders across eight administrations. From JFK's assassination to agents with MAGA hats, this bestseller reveals how America's elite guardians endangered the presidents they swore to protect.
Carol Duhurst Leonnig, Pulitzer-winning investigative reporter and bestselling author of Zero Fail: The Rise and Fall of the Secret Service, is a national authority on presidential security and political accountability. A staff writer at The Washington Post since 2000, Leonnig’s expertise in uncovering institutional failures stems from her groundbreaking reporting on the Secret Service, which earned her the 2015 Pulitzer Prize for National Reporting.
Her work, including co-authored New York Times bestsellers A Very Stable Genius and I Alone Can Fix It (with Philip Rucker), dissects modern presidential leadership and crises, blending meticulous research with insider accounts.
Zero Fail, a gripping exposé of the Secret Service’s cultural and operational decline, draws on over 180 interviews to explore themes of duty, secrecy, and the tension between security and democracy. Leonnig’s contributions to The Post’s Pulitzer-winning coverage of the January 6 insurrection and Russian election interference further cement her reputation.
A frequent NBC News and MSNBC analyst, her books have shaped public understanding of power dynamics in Washington. Zero Fail became an instant New York Times bestseller, praised for reshaping conversations about national security reform.
Zero Fail by Carol Leonnig exposes the U.S. Secret Service’s institutional decline, chronicling toxic workplace culture, high-profile failures (like the Reagan assassination attempt and 2012 "Hookergate" scandal), and politicized leadership. Leonnig traces these issues from JFK’s era to Trump’s presidency, revealing how the agency prioritized reputation over security.
This book suits true crime enthusiasts, political history buffs, and readers interested in institutional accountability. It’s ideal for those seeking a critical analysis of federal agencies or behind-the-scenes insights into presidential security failures.
Yes. Pulitzer winner Carol Leonnig combines meticulous research with gripping storytelling, offering unprecedented access to Secret Service scandals and systemic dysfunction. Kirkus Reviews calls it a “damning portrait” essential for understanding modern security vulnerabilities.
Key scandals include:
Leonnig highlights poor accountability, outdated training, and leaders who prioritized presidential whims over safety. For example, Trump pressured agents to remove Melania’s detail head over footwear preferences, while post-9/11 underfunding strained teams.
Leonnig relies on internal documents, interviews with retired agents, and whistleblower accounts. She details unreported incidents, like armed intruders breaching White House grounds during Obama’s tenure.
The book describes systemic racism, including a noose found in a Black instructor’s workspace. Leadership dismissed it as “one bad apple,” ignoring broader cultural issues.
The title refers to the Secret Service’s unofficial mandate to prevent any security lapse. Leonnig argues this impossible standard bred a culture of secrecy and blame-shifting.
Unlike celebratory histories, Leonnig’s investigative approach emphasizes institutional decay. It’s frequently compared to In the Secret Service by Jerry Parr but offers a more critical, modern perspective.
While focused on physical security, the book underscores universal themes: underfunded agencies risk catastrophic failures, and leadership accountability is vital. These insights apply to cybersecurity and organizational management.
As a Pulitzer-winning Washington Post reporter, Leonnig leverages investigative rigor and insider access. Her narrative blends historical context with firsthand agent testimonies, creating a balanced yet damning account.
The book exposes ongoing vulnerabilities in presidential protection, especially amid rising threats and politicized security agencies. Its insights into Trump’s interference with Secret Service protocols remain timely.

A gunshot cracks through the air. Agent Tim McCarthy doesn't duck-he spreads his arms wide and turns toward the shooter, making his body a human shield. The bullet tears into his midsection as President Reagan crumples into the limousine. This is the Secret Service at its finest: instant, selfless action in the face of death. Yet decades later, a Delta Force sergeant major would deliver a crushing verdict to Counter Assault Team member Brad Gable: "The Service has really let you down. You'll never be able to stop a real attack." How did an agency built on such extraordinary courage become what insiders now call "a paper tiger"? The truth is uncomfortable. Behind the sunglasses and earpieces lies an organization crippled by leadership failures, budget constraints, and a culture that rewards loyalty over competence. Through hundreds of interviews with agents, directors, and presidents, a disturbing pattern emerges: the Secret Service learns only through bloodshed, implementing reforms after assassinations rather than preventing them. November 22, 1963, should have been routine. Instead, it became the day that exposed just how vulnerable American presidents really were. The Secret Service protecting Kennedy resembled a modest city police force more than an elite protective unit-just thirty-four agents assigned to the White House detail, no specialized training program, and protocols learned through informal mentoring rather than rigorous instruction. Kennedy himself had stacked the odds against his protectors. His frenetic travel schedule forced agents to work double shifts with minimal rest, while he regularly ordered them to keep their distance during public appearances. "He couldn't get elected dogcatcher if he didn't mingle with crowds," agents recalled him saying. The night before the assassination, nine agents-including four scheduled for early morning duty-stayed out drinking until 5 a.m., violating regulations routinely ignored throughout the Service. When the shots rang out, only Clint Hill recognized what was happening. He sprinted toward the limousine as a third bullet exploded Kennedy's skull, clinging to the accelerating vehicle and pressing Mrs. Kennedy back into her seat while shielding the couple with his body. Looking down at the catastrophic head wound, Hill gave his teammates a thumbs-down. The unthinkable had happened, and the world would never be the same.
