After meeting with the president in the Oval Office for about a half hour, Gen. Stanley McChrystal left the White House at about 10:26 A.M. EST. He was supposed to attend the monthly strategy session in the Situation Room at 11:35 A.M. EST, so the fact that he left the before that meeting could mean something. Or it could mean nothing.

UPDATE: McChrystal has yet to return for the meeting scheduled to begin a few minutes ago.
