President Kennedy was the first Catholic president and as such, dealt with concerns his election would give the the pope a greater political role. He was cautious as to when he and Pope Paul VI would meet. That occurred near the end of his first term, July 2, 1963.
WW II prevented President Roosevelt from meeting Pope Pius XI, but he did meet Cardinal Eugenio Pacelli in 1936 three years before Pacelli became Pope Pius XII.
