Report: Lockerbie bomber's release was motivated by oil deal

The report was released on the 22-year anniversary of the explosion of Pan Am Flight 103 over Lockerbie, Scotland. Al-Megrahi was convicted in 2001 of masterminding the bombing, which killed 270 people, 189 of which were Americans. He was released from prison in 2009 after Scottish doctors said he would live no more than three months. Al-Megrahi went back to Libya, where he remains to this day.

The report says the medical diagnosis on which al-Megrahi’s release was based “was inaccurate and unsupported by medical science.”

Menendez invited officials from BP, as well as the Scottish and U.K. governments to testify at a hearing in September on al-Megrahi’s release. All the officials declined the invitation.

A BP spokesman directed The Hill to the company's August 2010 response to the senators' questions about al-Megrahi's release. "To be clear, the decision to release Mr. Al Megrahi on compassionate grounds was made by the Scottish Executive alone, without any involvement by BP and without any communications from BP seeking the release of Mr. al-Megrahi," the company said.
