MVS Radio said Sunday that Carmen Aristegui was removed for challenging the firing of two reporters who had misused the company's name by suggesting it was a sponsor of MexicoLeaks, a Wikileaks-like website meant to reveal leaked information on corruption in Mexico. [...] defenders of Aristegui noted that the firing came a few months after the same reporters had embarrassed President Enrique Pena Nieto by revealing his wife was purchasing a house with financing from a frequent government contractor. The report was one of several blows to the president's image, including criticism of its investigation in the disappearance and presumed death of 43 teachers' school students, who were apparently seized by city police and turned over to a drug gang.
