Ricardo Salinas Pliego, the owner of TV Azteca, the second biggest broadcaster in Mexico, just can’t seem to win.

He is under investigation in Mexico and already charged by the U.S. Securities and Exchange Commission over allegations of wrongdoing in relation to the mobile phone company that he owns.

Now, his broadcasting operation is trading charges with the Mexican government over a documentary aired by the network.

The documentary in question accuses the government of wrongdoing in the acquisition by Citigroup of Mexican bank Grupo Financiero Banamex.

The documentary claims that the purchase was beset by financial irregularities. Banamex has denied the charges made in the documentary, calling them “baseless.”

Now, TV Azteca is accusing the Mexican finance minister of threatening charges of violation of securities laws against the network if they broadcast the program.

Jorge Mendoza, TV Azteca’s head of news and public affairs, says he was summoned to the finance minister’s office on Tuesday and given a written demand to either refrain from airing the program or face possible charges from the attorney general’s office.

The documentary aired Tuesday night on TV Azteca, and on Wednesday the networks news anchor, accused the finance minister of violating the network’s freedom of speech.
