RIO DE JANEIRO, Nov 24 (Reuters) - Brazil's state-run oil firm Petroleo Brasileiro SA said on Monday it had received a subpoena from the U.S. Securities and Exchange Commission asking for documents relating to an investigation it is pursuing.
Petrobras, as the firm is known, said the requested material would be sent and it was working with the law firms Trench, Rossi and Watanabe, and Gibson, Dunn & Crutcher, which have already been hired to lead an internal investigation into allegations of corruption at the company.
