A key minister in Brazil's new government steps aside after he was caught on tape allegedly conspiring to obstruct a major corruption probe. Planning Minister Romero Juca was caught on tape allegedly conspiring to obstruct the country's biggest-ever corruption investigation. Dilma Rousseff said the tapes prove that the impeachment process is a "political coup" designed to protect senior figures implicated in the Petrobras scandal. She is accused of massaging budget figures ahead of her re-election in 2014, and is due to be tried in the senate in the coming months. The context of the conversation appears to be Brazil's political crisis, and he seems to be talking about preventing further investigations into Petrobras.
