Gen. James Jones, President Barack Obama's national security adviser, is stepping down and will be replaced by his top deputy Tom Donilon, two senior administration officials told The Associated Press on Friday.
Obama will announce the change in a Rose Garden ceremony on Friday with both men. Jones' resignation will take effect in two weeks.
The move, though expected, is the latest high-profile departure among Obama's leadership team. Chief of staff Rahm Emanuel left just last week, and the president is expected to see more change at the top as Obama's tenure nears the two-year mark and the grinding pace of the White House takes a toll.
