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)

The ease with which Cuba slipped into its relationship with Communism revived in the United States its recurring nightmare in which other Latin American countries, particularly Mexico, become satellites of Russia or Red China. But such an occurrence is most unlikely in Mexico, according to Karl Schmitt, former intelligence research analyst with the United States Department of State. Communism in Mexico traces efforts during the early twentieth century to create a Soviet-style society in one of the largest and most strategically situated of the Latin American countries. Schmitt writes authoritatively of the Mexican Communist movement, tracing its development from an early and potentially powerful political-economic base to the increasingly fragmented and weakened collection of parties and front groups of the 1960s. He follows the various schisms and factional divisions to the mid-1950s, when the process of disintegration became most noticeable, and explores and analyzes in detail Communist attempts since then to establish unity among the many quarreling and frustrated groups of the now-splintered movement. Three Communist parties in Mexico, a score of front groups, and numerous infiltration cells in non-Communist organizations such as student and labor groups, all recognize in a broad way a common and ultimate goal: the creation of a Soviet-style society. But their attempts at unity have consistently led only to further bickering and frustration. This period is subjected to a thorough study and analysis in an effort to understand and explain the Communists' lack of success. Schmitt presciently concludes that Communism's future in Mexico will be as cloudy as its past, and that the accelerating economy and improving social conditions there will serve to weaken the movement still further.
