Four US Senators want the state department to investigate whether BP played a role in last year’s release of a terrorist convicted in the Lockerbie bombing.

Abdel Baset al-Megrahi was released from a Scottish prison after he was diagnosed with a terminal illness.

The doctor who examined him now says he was paid off by the Libyan government.

All four senators from New York and New Jersey are asking the federal government to look into reports that BP helped secure al-Megrahi’s release in order to finalize a $900 million offshore oil drilling deal with Libya.
