Peña Nieto joined the Institutional Revolutionary Party (PRI) in 1984, and with a law degree nearly completed, he began earning his own money. During his final years in college, Peña Nieto worked for a public notary in Mexico City, around the same time when his relative, Alfredo del Mazo González, was mentioned as a firm candidate for the 1988 presidential elections. In his twenties, he worked at the San Luis Industrial Corporation, an auto parts manufacturer, and at the law firm Laffan, Muse and Kaye. While still a student at the Universidad Panamericana, he roomed with Eustaquio de Nicolás, the current president of Homex, a leading Mexican construction and real estate company. He also befriended and roomed with Luis Miranda, who occupied several offices during the 1999–2000 administration in the State of Mexico.
