Book excerpt: In some periods of American history, members of the legislative branch have been as influential, and sometimes more influential, than a particular president in crafting public policy and reacting to world events. Congressional Lions examines twelve influential members of Congress throughout American history to understand their role in shaping the life of the nation. The book does not focus exclusively on the biographical details of these lawmakers, although biography invariably plays a role in recalling their triumphs and tragedies. Instead, the book highlights members’ legislative accomplishments as well as the circumstances surrounding their congressional service.
