 After leaving the House and returning to private medical practice, Coburn wrote "Breach of Trust", with ghostwriter John Hart, about his experiences in Congress.The book detailed Coburn's perspective on the internal Republican Party debates over the Contract With America and displayed his disdain for career politicians.Some of the figures he criticized (such as Gingrich) were already out of office at the time of the book's publishing, but others (such as former House Speaker Dennis Hastert) remained influential in Congress, which resulted in speculation that some congressional Republicans wanted no part of Coburn's return to politics.
