Kai Bird has spent a career writing about the men who shaped American power from just outside the frame of respectability, and in American Scoundrel, co-written with Susan Goldmark, he turns that lens on Roy Cohn, the lawyer and fixer whose fingerprints, the book argues, are still legible on American political life decades after his death. The subtitle does the framing work: this is Cohn’s dark journey from Joseph McCarthy to Donald Trump, and the book’s central claim is that those two names are not bookends but a single continuous line.
Bird, a Pulitzer Prize-winning biographer whose previous work traced the moral compromises of Cold War operatives, approaches Cohn less as a curiosity than as a case study in how a certain style of American ambition gets built and rewarded. The early chapters move through familiar but well-told territory: Cohn’s rise as a prosecutor, his central role at McCarthy’s side during the Army-McCarthy hearings, and the particular brand of aggressive, shameless combativeness that made him simultaneously reviled and indispensable to the powerful people who kept hiring him anyway.
What distinguishes this biography from earlier accounts is the back half, which follows Cohn’s years as a private fixer for New York’s wealthy and connected, including a young Donald Trump, whom Cohn mentored through his earliest legal battles and, the book argues, helped shape into a particular kind of combatant: attack, never apologize, flood every dispute until the other side exhausts itself. Bird and Goldmark are careful biographers rather than polemicists here; the throughline to more recent politics is present but is built from documented episodes and named sources rather than asserted as a given.
Critical reception has focused heavily on the book’s timing and its argument rather than on any dispute over its research, which draws on extensive archival work and interviews consistent with Bird’s earlier books. Reviewers have generally credited the authors with resisting the temptation to turn Cohn into a cartoon villain, instead rendering him as coherent and, in his own terms, successful, which several critics have called the more unsettling choice. Some have wished for a more expansive treatment of Cohn’s personal life and his years of concealment around his own identity while he supported policies hostile to it, a tension the book acknowledges but does not linger on as long as some readers might want.
Taken as a whole, American Scoundrel reads as both a biography and an argument about method: that the tactics one man perfected in the McCarthy era did not die with him, but were passed down, refined, and eventually normalized. Whether or not every reader accepts the full weight of that argument, the book earns its place as one of the more clearly reported attempts yet to draw a straight line between Cohn’s era and this one.
