WASHINGTON — Gen. James Jones is resigning as President Barack Obama's national-security adviser, two senior administration officials said.
Jones will be succeeded by Tom Donilon, the deputy national security adviser, the sources said.
Obama will announce the change Friday afternoon in a Rose Garden ceremony with Jones and Donilon.
Jones, whose resignation will be effective in two weeks, had planned from the start of his tenure to leave the position at about the two-year mark, the officials said.
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.
Jones, who retired from active duty in February 2007 after more than 40 years of uniformed service, had planned all along to leave the national security adviser's post within two years, said one official. The officials spoke on condition of anonymity because the president had not yet announced the decisions.
Donilon's promotion has a significant spillover effect on the rest of the White House. He had emerged as a top candidate to replace Emanuel as the permanent chief of staff. Now that job appears even more likely to go to Pete Rouse, the newly installed interim chief of staff and a longtime adviser to Obama.
Donilon has played a leading role in the policymaking process that tees up the national security decisions for the president. He has overseen the coordination among deputy chiefs from across the security apparatus and is known for bringing an understanding of domestic policy and politics to the job.
Jones, meanwhile, has largely kept a low public profile. White House aides say he put his stamp on Obama's major foreign policy decisions over the last 20 months, included a beefed-up troop presence in Afghanistan, a winding down of the war in Iraq and a retooled relationship with Russia.
Jones served as the 32nd Marine Corps Commandant from July 1999 to January 2003. After leaving the post, he became the Supreme Allied Commander, Europe, and Commander of the United States European Command, holding the positions until December 2006.
Besides his combat experience in Vietnam, Jones served tours of duty during Operation Provide Comfort in northern Iraq and Turkey as well as during operations in Bosnia-Herzegovina and Macedonia.
Administration officials said they expect him to go into a semiretirement in which he will likely serve on boards and offer counsel to the White House.
