Senator Richard Nixon, against attacks by his mother – caused considerable family friction. The tension was exacerbated when Roosevelt and his family moved into Stone Cottage next door to Eleanor Roosevelt's home at Val-Kill that same year. He and his brother, Elliott, who lived at nearby Top Cottage, did not get along. Elliott left shortly after John and his family arrived. John subsequently acquired what remained of the Hyde Park property Elliott had farmed with Eleanor Roosevelt. More importantly, the presence of John and his family enabled Eleanor Roosevelt to live at Val-Kill until her death in 1962. She saw John's children often and was particularly close to his daughter, Sara "Sally" Roosevelt.

At Bache, he managed the Teamsters Union pension funds and was a friend and vocal defender of Jimmy Hoffa until the latter's incarceration. His philanthropic activities included serving as a fund raiser with the National Foundation for Infantile Paralysis, which his father had founded, membership on the executive committee of the Greater New York Council of the Boy Scouts of America and service as a trustee of the State University of New York. Within three years of Eleanor Roosevelt's death, John Roosevelt divorced and remarried. In 1970, he sold
