Miller began working in the
United States House of Representatives in 1933 as a clerk in the House's Post Office. When Miller drew office assignments for House members, he was known to sand his fingertips in order to identify the discs he was drawing and ensure that Democratic members received desirable offices. Miller also functioned in the role by escorting visiting foreign dignitaries. A 1950 profile in
The New York Times described Miller as "odd-jobs man for his 435 bosses", mentioning that he functioned as "baby-sitter, cigar-lighter, gum-giver and even water boy". He earned $40,000 a year, $2,500 less than a congressperson. In 1974, Miller faced competition for his job for the first time since 1949. he was ousted and replaced by
James T. Molloy. Upon leaving the post, Miller remarked, "I have lived a good life, a full life", and, "I have enjoyed every minute of it and as I leave I have no regrets and no axes to grind". ==Personal life==
