Lockerbie bomber dominates PM Cameron's US visit
The Scottish government's decision to release the Lockerbie bomber last August is expected to overshadow UK Prime Minister David Cameron's first official visit to the US.
Both Mr Cameron and President Obama agree the release of Abdelbaset al-Megrahi was wrong, but US politicians are asking for an inquiry into the decision.
The leaders are also expected to discuss the situation in Afghanistan, and the Gulf of Mexico oil leak.
