Before his first meeting with the President today, British Prime Minister David Cameron sat down for an interview with ABC News' Diane Sawyer. The hot topic was the controversy over Scotland's release of convicted Pan Am 103 bomber Abdelbaset al-Megrahi, who was returned home to Libya on "compassionate" grounds last year because he has pancreatic cancer. But Megrahi is still alive, and there's speculation that BP played a role in his release to win lucrative oil contracts in Libya.

While acknowledging that Megrahi's release was a mistake, Cameron still insists that BP had no influence on Scotland's decision. Nevertheless, in an attempt to soothe ruffled feathers here, Cameron announced that he's "asking the cabinet secretary in the UK to go back over all the paperwork and see if there's anything else that should be released so there's the clearest possible picture out there of what decision was taken and why." BP has admitted that it lobbied for a prisoner swap between Libya and the UK, but the company says it never specifically pushed for Megrahi's release, nudge nudge, wink wink.

Cameron also said, "I don't need an inquiry to tell me what I think I already know, which is it was a bad decision to release him and it was a bad decision to even contemplate this. He was convicted of the biggest mass murder in British history. In my view that man should have died in jail." Senators from New York and New Jersey, where the majority of the victims were from, formally called on Cameron to meet with them personally during his visit, and after initially declining, he decided to make room in his schedule.

Secretary of State Hillary Clinton, who has also called on Scotland and Britain to review Megrahi's release, has said that the the decision on whether to release him fell exclusively to the Scottish government under local law. Scottish Justice Minister Kenny MacAskill stands by his decision, and said, "I reflected and followed the rules and laws of Scotland." And in a letter to Congress, British Foreign Secretary William Hague said, "There is no evidence that corroborates in any way the allegations of BP involvement." During a White House press conference following his three hour meeting with Cameron, President Obama called America's relationship with the UK "truly special."
