President Obama and Prime Minister Brown spoke on the phone for about 40 minutes this afternoon. Their talk encompassed a variety of topics including Afghanistan, the upcoming G20 summit in Pittsburgh and the recent release of Pan Am Bomber al-Megrahi.

Although a Downing Street spokesman called the conversation "warm and substantive", the White House readout also mentioned that President Obama had "expressed his disappointment" over the Scottish Executive’s decision to release convicted Pan Am 103 Bomber al-Megrahi back to Libya. This was first conversation the two leaders have had since al-Megrahi's release. White House Press Secretary Robert Gibbs did not reveal anymore about this portion of the conversation during today's briefing with reporters, except to say that President Obama thought the release was a "mistake" and "continues to think this is a mistake." Although Mr. Gibbs would not comment on Prime Minister Brown's reaction to President Obama's mention of "disappointment" over the issue, he did say the President was satisfied with the response from Brown, while restating his opposition to the decision made.

Here is the White House readout from today's phone call:
