Washington (CNN) - President Barack Obama has informed several top diplomatic and military officials about his decision regarding new U.S. strategy and troop levels in Afghanistan, White House Press Secretary Robert Gibbs said Monday.
Obama called Secretary of State Hillary Clinton on Sunday to tell her about his decision, Gibbs said. He also informed his top military commander in the country - Gen. Stanley McChrystal - and Karl Eikenberry, the U.S. ambassador to Afghanistan.
On Tuesday, Obama will travel to West Point, New York, to announce his decision on a request by McChrystal for up to 40,000 additional troops.
Obama is expected to send more than 30,000 U.S. troops and seek further troop commitments from NATO allies as part of a counterinsurgency strategy to wipe out al Qaeda elements and stabilize the country while training Afghan forces.
