Congressman Andre Moura of the conservative Social Christian Party is also being investigated for alleged involvement in the corruption-kickback scheme at state-owned oil company Petrobras.
Moura told reporters yesterday that the attempted murder accusations against him are unfounded and made by a political rival in the state of Sergipe to ruin his career. He also denied any involvement in the corruption at Petrobras.
Prosecutors say more than USD 2 billion was paid in bribes and other funds by Brazil's biggest construction and engineering firms in exchange for inflated Petrobras contracts.
