U.S. senators who risked their careers for their personal beliefs, for which he won the Pulitzer Prize for Biography in 1957. Rumors that this work was co-written by his close adviser and speechwriter, Ted Sorensen, were confirmed in Sorensen's 2008 autobiography. At the start of his first term, Kennedy focused on Massachusetts-specific issues by sponsoring bills to help the fishing, textile manufacturing, and watchmaking industries. In 1954, Senator Kennedy voted in favor of the Saint Lawrence Seaway which would connect the Great Lakes to the Atlantic Ocean, despite opposition from Massachusetts politicians who argued that the project would cripple New England's shipping industry, including the Port of Boston. Three years later, Kennedy chaired a special committee to select the five greatest U.S. senators in history so their portraits could decorate the Senate Reception Room. That same year, Kennedy joined the Senate Labor Rackets Committee with his brother Robert (who was chief counsel) to investigate crime infiltration of labor unions.

The bill dealt largely with the control of union abuses exposed by the McClellan committee but did not incorporate tough Taft–Hartley amendments requested by President Eisenhower. It survived Senate floor attempts to include Taft-Hartley amendments and gained passage but was rejected by the House. At the 1956 Democratic National Convention, Kennedy gave the nominating speech for the party's presidential nominee, Adlai Stevenson II. Stevenson let the convention select the vice presidential nominee. Kennedy finished second in the balloting, losing to Senator Estes Kefauver of Tennessee but receiving national exposure as a result.

Kennedy also voted for Title IV, termed the "Jury Trial Amendment". Many civil rights advocates at the time criticized that vote as one which would weaken the act. A final compromise bill, which Kennedy supported, was passed in September 1957. He proposed on July 2,
