Minutes later, in a different ceremony, Peña Nieto conducted the oath of office of the members of the new Security Cabinet, composed of Miguel Angel Osorio Chong, as the head of the Ministry of the Interior, Salvador Cienfuegos Zepeda as head of the Ministry of National Defense and Vidal Soberon Sanz as Secretary of the Navy. Peña Nieto, who heads the Institutional Revolutionary Party, known as the PRI, said the new government had taken office "from the first minute of this day." "A governmental transition has been completed in an orderly, legal and transparent fashion," he said. "This process has helped to preserve the political stability, economic and social development of the nation. Mexico has shown democratic maturity and institutional strength. In accordance with Article 83 of the constitution, today I begin to exercise the honorable position of President of the United States of Mexico." Both man made use of social media to voice their thoughts during this historic moment in Mexican history. Calderon said via Twitter: "My term ends, but not my commitment to Mexico, which I will continue fighting until the last of my days. Another tweet read: "The handover of the national flag for the change of guard from the president to the president-elect symbolizes the transfer of command." Peña Nieto tweeted: "Starting today, I begin to occupy the post of Constitutional President of the United Mexican States. I am confident in my team and I recognize their track record, which supports its commitment to Mexico." He will take the oath of office in the lower house of Congress at 10 a.m. local time Saturday, under tight security.
