Prime Minister David Cameron makes his first White House visit as Britain's leader Tuesday.
Cameron became prime minister in May. Topics he is expected to discuss with President Barack Obama will include the war in Afghanistan and last year's release by Scotland of the Libyan man convicted in the 1988 Lockerbie airplane bombing, White House Press Secretary Robert Gibbs said Monday.
Britain is a leading ally in the U.S.-led military coalition fighting Taliban insurgents in Afghanistan. However, Cameron is under pressure at home to end the British involvement in the campaign.
"I think the president has, on a number of occasions, laid out why what he's doing in Afghanistan is in our national security interests. We will continue to make that case tomorrow," Gibbs told a news briefing. "Obviously, we have, in both this administration and in the previous administration, had the help of the British government. I think both they and we have said we will not be there forever."
Gibbs also said the release last August of Abdelbaset Ali Mohmed al Megrahi, who was sentenced to life for his role in the bombing of Pan Am Flight 103 over Lockerbie, Scotland, would come up at Tuesday's meeting. The Pan Am bombing killed 270 people, most of them Americans.
