Mexican President Felipe Calderon says former President Miguel de la Madrid Hurtado is in grave condition.
Rumors had spread earlier Saturday that the former president had died, and Calderon had sent his condolences via Twitter. Mexican newspapers and even presidential candidate Enrique Pena Neto had commented on de la Madrid's supposed death.
Calderon's Twitter account later emphasized that the 77-year-old former president's family said he had not died. Calderon also wrote that de la Madrid had been hospitalized for respiratory problems.
De la Madrid was president from 1982 to 1988, as the country suffered hyperinflation and other economic crises. He also led the country during a devastating 1985 earthquake.
