SAO PAULO (AP) The board of directors for Brazilian oil firm Petrobras is meeting Friday and is expected to name a new chief executive officer later in the day.

Brazil's state oil company is in crisis amid an expanding corruption investigation into a long-running kickback scheme on its contracts.

Several top executives from Brazil's biggest construction and engineering firms already are jailed and charged, along with a handful of former Petrobras executives.

It was on Wednesday that CEO Maria das Gracas Foster and five other top Petrobras executives resigned. None are facing charges in the corruption scandal but authorities say the investigation is still in its beginnings stage.

Prosecutors say the kickback scheme involved at least $800 million in bribes and other illegal funds in exchange for inflated Petrobras contracts.
