Petrobras scandal: President Rousseff "benefitted politically" Brazilian President Dilma Rousseff “benefitted politically” from bribes by Petrobras between 2004 and 2012, along with dozens of MPs and senators of the coalition in power, said presidential candidate Aecio Neves on Friday in Rio de Janeiro. Social democrat Neves was running second in the polls but when socialist candidate Eduardo Campos died, he was displaced by new candidate Marina Silva who is now neck-and-neck with Dilma Rousseff.
