In nominating Calderon to be the commencement speaker, Stanford student leaders said they wanted to send a message about the need for leadership in international cooperation and social justice.

Calderon was elected to a six-year term as Mexico’s president in 2006. He previously served as president of Mexico’s National Action Party and as secretary of energy in former President Vicente Fox’s administration.
