Costa, who is currently in prison and under investigation for involvement into the corruption, has named Minister, governors and Congressmen. Part of them were members of the ruling Working Party, which could seriously damage President Dilme Roosef.
Many names were published in Veja, one of the leading magazines in Brazil. Some politicians have already denied the accusations. Costa was arrested in 2013 and before naming the politicians he has concluded a deal with the investigation.
