Brazil's Rousseff fires back after graft allegations

Brazilian President Dilma Rousseff ordered a criminal complaint filed against a senator who accused her of benefiting from a huge corruption scheme at state oil company Petrobras.
"President Dilma Rousseff ordered all due legal measures be taken against Mr Delcidio do Amaral, to hold him responsible under the law for all his defamatory statements," Rousseff's office yesterday said, after the senator told a magazine that she knew about the Petrobras graft and used some of the proceeds in her election campaigns.
