The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)

Some vols. include supplemental journals of "such proceedings of the sessions, as, during the time they were depending, were ordered to be kept secret, and respecting which the injunction of secrecy was afterwards taken off by the order of the House."

In this startling, intensively researched book, bestselling historian Paul Kengor shines light on a deeply troubling aspect of American history: the prominent role of the "dupe." From the Bolshevik Revolution through the Cold War and right up to the present, many progressives have unwittingly aided some of America's most dangerous opponents. Based on never-before-published FBI files, Soviet archives, and other primary sources, Dupes exposes the legions of liberals who have furthered the objectives of America's adversaries. Kengor shows not only how such dupes contributed to history's most destructive ideology—Communism, which claimed at least 100 million lives—but also why they are so relevant to today's politics.
