Brazil's senate president denies blocking corruption probe
BRASILIA, June 7 (Reuters) - The president of Brazil's Senate, Renan Calheiros, denied that he has sought to obstruct an investigation into a graft scheme at state-run oil company Petrobras, following a newspaper report on Tuesday that the country's top prosecutor has sought his arrest.
Calheiros said in a statement that the reported arrest request was "unreasonable, disproportionate and abusive."
