Corruption in Brazil
In 2014, a top former executive at Petrobras, the state-run oil company, told investigators the company had been sending bribes from oil contracts to senior politicians. Many of the accused politicians are members of Rousseff's Workers Party or her ruling coalition. Rousseff has denied any involvement, and the attorney general clear her. But she chaired Petrobras's board of directors during much of the period of the kickbacks, which allegedly totaled around $3.8 billion.
