Dating a diplomat
Trujillo recognized what an asset Rubirosa was for his regime, remarking: "He is good at his job, because women like him and he is a wonderful liar." After Trujillo's assassination on May 30, 1961, Rubirosa supported his son as successor and attempted to persuade John F. However, when Ramfis Trujillo and his family fled the Dominican Republic, Rubirosa's career came to an end.
He was an adherent of the dictator Rafael Trujillo, and was also rumored to be a political assassin under his regime.
Rubirosa entered one Formula One race, in 1955, the Grand Prix de Bordeaux on April 25.
He planned to drive his own Ferrari 500, identical to the one which brought Alberto Ascari the 19 Drivers' World Championship.
He organized and led his own polo team Cibao-La Pampa that was an often successful contender for the Coupe de France. In the same period, he started to acquire fast cars and form friendships with racing car drivers. His first race at 24 Hours of Le Mans took place in June 1950 with his partner Pierre Leygonie, and his second race, this time with Innocente Baggio, was four years later; in both races his car did not finish.
Rubirosa participated in a number of races at Sebring, all but once as a private entry.
