President Bush is rejecting Syria's suggestion of a partial troop pull-back in Lebanon, saying, "Lebanon must be free."
At Social Security forums in New Jersey and Indiana, the president insisted Damascus must fully withdraw all its troops and intelligence agents from Lebanon.
He says the Lebanese are demanding real democracy -- and the world, "speaking with one voice", agrees.
Bush is returning to the issue in today's weekly radio address.
Syria's exercised effective control over Lebanon since the end of the Lebanese civil war in 1990. But the assassination of a former Lebanese prime minister last month has sparked street protest -- and fresh demands for a Syrian pull-out.
