McChrystal huddled first with Defense Secretary Robert Gates and Adm. Mike Mullen at the Pentagon for 30 minutes this morning.
On his way in to that meeting, McChrystal scolded reporters for asking if he'd submitted his resignation, telling them, "Come on, you know better than that! No."
Democrats said privately they fear it would make Obama look weak if he allows McChrystal to stay, but also recognize that starting anew would disrupt the administration's goals for Afghanistan and the region at a critical time.
Late Update: The White House sends word a few minutes before noon that the meeting on Afghanistan and Pakistan has begun in the Situation Room. All the evidence suggests McChrystal is not there in person, but we don't know if he might be attending on video conference as he has done from previous meetings. Aides won't say if Obama will address the press to announce his decision.
Newsy Update: Obama has scrapped the remainder of his day's schedule, including a meeting with senators. He'll deliver remarks in the Rose Garden at 1:30 p.m.
