input: In November 1951, Kennedy moved with his wife and daughter to a townhouse in Georgetown in Washington, D.C., and started work as a lawyer in the Internal Security Section of the Criminal Division of the U.S. Department of Justice; the section was charged with investigating suspected Soviet agents. In February 1952, he was transferred to the Eastern District of New York in Brooklyn to prosecute fraud cases. On June 6, 1952, Kennedy resigned to manage his brother John's successful 1952 U.S. Senate campaign in Massachusetts. JFK's victory was of great importance to the Kennedy family, elevating him to national prominence, and turning him into a serious potential presidential candidate. But his brother's victory was equally important to Robert, who felt he had succeeded in eliminating his father's negative perceptions of him. In December 1952, at the behest of his father, Kennedy was appointed by family friend Republican Senator Joseph McCarthy as assistant counsel of the U.S. Senate Permanent Subcommittee on Investigations, However, Kennedy disapproved of the senator's aggressive methods of garnering intelligence on suspected communists. This was a highly visible job for him. He resigned in July 1953, but "retained a fondness for McCarthy". The period of July 1953 to January 1954 saw him at "a professional and personal nadir", feeling that he was adrift while trying to prove himself to the rest of the Kennedy family. After a period as an assistant to his father on the Hoover Commission, Kennedy rejoined the Senate committee staff as chief counsel for the Democratic minority in February 1954. That month, McCarthy's chief counsel Roy Cohn subpoenaed Annie Lee Moss, accusing her of membership in the Communist Party. Kennedy revealed that Cohn had called the wrong Annie Lee Moss and he requested the file on Moss from the FBI. FBI director J. Edgar Hoover had been forewarned by Cohn and denied him access, referring to RFK as "an arrogant whipper-snapper". When the Democrats gained the majority in the Senate in January 1955, Kennedy became chief counsel and was a background figure in the televised Army-McCarthy Hearings of 1954 into McCarthy's conduct. The Annie Lee Moss incident turned Cohn into an enemy, which led to Kennedy assisting Democratic senators in ridiculing Cohn during the hearings. The animosity grew to the point where Cohn had to be restrained after asking RFK if he wanted to fight him. For his work on the McCarthy committee, Kennedy was included in a list of Ten Outstanding Young Men of 1954, created by the U.S. Junior Chamber of Commerce. His father had arranged the nomination, his first national award. In 1955, Kennedy was admitted to practice before the United States Supreme Court.

input: Initial successes with Whiteman were followed by disaster when they reached New York and Whiteman considered letting them go. Bing may have been retained as Whiteman was already using him as a solo performer on record, but the prospects for Rinker were bleak. However, the addition of pianist and aspiring songwriter Harry Barris made the difference and "The Rhythm Boys" were born. The additional voice meant the boys could be heard more easily in the large New York theaters and eventually became a success. A year touring with Whiteman performing and recording with musicians Bix Beiderbecke, Jack Teagarden, Tommy Dorsey, Jimmy Dorsey, Eddie Lang and Hoagy Carmichael, provided valuable experience and began touring. Crosby then matured considerably as a performer and was in constant demand as a solo artist. Crosby soon became the star attraction of the Rhythm Boys, and in 1928 he had his first number one hit with the Whiteman orchestra, a jazz-influenced rendition of "Ol' Man River". In 1929, the Rhythm Boys appeared in the film The King of Jazz with Whiteman but Bing's growing dissatisfaction with Whiteman led to the Rhythm Boys leaving his organization. They joined the Gus Arnheim Orchestra performing nightly in The Coconut Grove of the Ambassador Hotel. Singing with the Arnheim Orchestra, Bing's solos began to steal the show, while the Rhythm Boys act gradually became redundant. Harry Barris wrote several of Crosby's subsequent hits including "At Your Command", "I Surrender Dear", and "Wrap Your Troubles In Dreams". In the early months of 1931, a solo recording contract came Bing's way, Mack Sennett signed him to make film shorts and a break with the Rhythm Boys became almost inevitable. Bing had married Dixie Lee in September 1930 and after a threatened divorce in March 1931, he started to apply himself seriously to his career. His gramophone records in 1931 broke new ground as his powerful and emotional singing started to change the face of popular music forever. Their low salaries at the Cocoanut Grove of the Ambassador Hotel had led the Rhythm Boys to walk out, causing union problems for Bing. Bing's brother, Everett, interested Bill Paley of CBS in his brother and Paley beckoned Bing to come to New York. A settlement was reached with the Ambassador Hotel and Bing made his first solo national radio broadcast in September 1931 and then went on to star at the New York Paramount Theatre.
