Former Mexico Prez Dead at 77

President Felipe Calderon says on his Twitter account that former President Miguel de la Madrid has died at age 77. A spokeswoman for Calderon's office speaking on condition of anonymity because she was not authorized to speak to the press confirmed today that the message was posted by Calderon. Calderon says he is "profoundly sorry for the death of ex-President De la Madrid."

The cause of death has not been announced, but the former president has been hospitalized for respiratory problems since late last year. De la Madrid led Mexico from 1982 to 1988 as the country experienced economic crises and endured an earthquake that devastated the capital.
