Congress's investigations of Chotiner continued through much of 1956, and were eventually postponed until after the election. The Senate subcommittee finally issued its report on September 5, 1957, placing no blame on Chotiner. The House investigation dragged on until 1958, by which time the focus of the investigation was on White House Chief of Staff Sherman Adams, who had sent Chotiner two letters regarding the airline matter. Nixon parted ways with Chotiner after the Senate testimony, calling his predicament "a tragedy", but by 1959, the two were friends again. Senator Knowland considered hiring Chotiner to manage his 1958 run for governor, but did not do so, and lost to Edmund G. "Pat" Brown. Chotiner would play no visible role in the unsuccessful 1960 Nixon presidential campaign. Despite his status as a political outcast, Nixon's former campaign manager remained loyal to him, and remained convinced Nixon would one day be president.
