Bugging Equipment Found in Mexico Lawmaker Offices A Mexican legislator says a search of several lawmakers' offices turned up recording equipment, leading legislators to believe they have been spied on for years. Congressman Armando Rios says security personnel found microphones and other devices that seemed to have been installed years ago. Chamber of Deputies president Guadalupe Acosta says the offices belong to lawmakers from different political parties. Acosta hasn't said who he thinks is behind the espionage. The government of President Felipe Calderon has denied involvement.
