Ex-president to be questioned in Brazil corruption probe

The ruling came on a request filed by investigators Sept. 11 who said they wanted to question Silva about possible involvement in the scheme. Under Brazilian law, all federal politicians and some at other levels can be investigated only if the Supreme Court approves the inquiry.

Brazil's former chief-of-staff charged with corruption

Corruption, racketeering and money laundering charges against Jose Dirceu were filed on Friday.

Sixteen other people were charged, including Joao Vaccari Neto, the former treasurer of Brazil's governing Workers' Party and Renato de Souza Duque, Petrobras' former head of corporate services.

Dirceu is the most senior member of the ruling Workers' Party to be taken into custody in connection with the scheme.
