Carmen Aristegui fired from MVS radio, likely for Calderón alcoholism rumours

Yesterday, MVS radio abruptly announced that Carmen Aristegui, a star of the network and one of the leading journalists in Mexico, was fired from her job. There was not even any "resignation-for-personal-reasons" dressing; MVS gave as reason that she "had broken the ethics code of the company."

It is very likely due to this statement, said after radical PT  and PRD deputies hung up a banner alluding to Felipe Calderón's rumored - with emphasis on rumored - alcoholism

"Really, the Presidency of the Republic itself should give clear, crisp, formal answer in this regard. There is nothing offensive  - it seems to me - when someone, if this is the case, is going through a problem of this kind... Does Felipe Calderón have a alcohol problem? Again, this deserves a serious response, formal and official from the Presidency of the Republic itself."

Without knowing much of this case or these rumors, as a matter of principle I tend to disagree with the logic of such statements. Why is the president forced to prove a negative - to prove something that he isn't? To put it this way: Following this logic, does he also have to prove he is not the flying spaghetti monster?

That said: Did Aristegui really deserve to be fired from saying what she did? I think not.
