# Roy Cohn influence on Donald Trump > Live situation record from CLSTR: https://clstr.news/situations/roy-cohn-influence-on-donald-trump > Updated: 2026-09-20T03:18:05.000Z. Sources: 6. Developments: 4. Recent accounts have examined the historical influence and personal character of lawyer Roy Cohn, specifically regarding his relationship with Donald Trump. Cindy Adams provided personal recollections of Cohn, describing his personality and habits. She noted that during periods of legal difficulty, Trump expressed a desire for Cohn’s presence, asking, “You remember what Roy said?” Historian Kai Bird and Susan Goldmark, in the biography ‘American Scoundrel’, further explored this connection. The authors characterize Cohn as a “nefarious, minor, awful figure” who acted as a mentor and fixer. The book examines parallels between Cohn’s legal and political tactics—developed during his time as chief counsel to Senator Joe McCarthy and as a lawyer for Trump during early housing discrimination allegations—and those of Donald Trump. In an interview on NPR’s ‘Fresh Air’, Bird expanded on these connections, noting that Cohn frequently attacked judges by name and operated under the belief that rules applied to others but not to him. Bird suggests that Cohn’s specific tactics—such as never admitting wrongdoing, constant denial of allegations, and using legal delays to obstruct proceedings—became a blueprint for Trump’s approach to the presidency and legal challenges. Bird also noted that Cohn’s ability to avoid consequences during his own indictments in the 1960s may have been due to luck, such as mistrials caused by unexpected personal emergencies involving jurors or lawyers. ## Timeline ### 2026-09-20: Roy Cohn’s legal playbook served as a model for Donald Trump Author Kai Bird’s new book, ‘American Scoundrel’, argues that lawyer Roy Cohn’s aggressive legal and political tactics served as a model for Donald Trump. 2 sources. https://clstr.news/cluster/roy-cohns-legal-playbook-served-as-a-model-for-donald-trump ### 2026-09-08: Roy Cohn biography explores influence on Donald Trump Kai Bird and Susan Goldmark’s new biography, “American Scoundrel,” explores the life of lawyer Roy Cohn and his significant influence on the political methods of Donald Trump. 2 sources. https://clstr.news/cluster/roy-cohn-biography-explores-influence-on-donald-trump ### 2026-08-28: Roy Cohn's influence on Donald Trump explored by historian Kai Bird Historian Kai Bird explores the lasting political influence of Roy Cohn on Donald Trump, detailing Cohn’s role as a mentor and his impact on contemporary American political culture. 2 sources. https://clstr.news/cluster/roy-cohns-influence-on-donald-trump-explored-by-historian-kai-bird ### 2026-08-09: Roy Cohn's history recounted by Cindy Adams Cindy Adams recounts her personal history with lawyer Roy Cohn, including his relationship with Donald Trump and his notorious professional and personal habits. 2 sources. https://clstr.news/cluster/roy-cohns-history-recounted-by-cindy-adams --- Cite as: Roy Cohn influence on Donald Trump.
