President Barack Obama will huddle with his national security team on Monday evening to discuss several policy options for Afghanistan and Pakistan.

The unexpected meeting is fueling speculation that a final decision on Afghanistan may be imminent.

The White House updated the president's schedule Monday morning to reflect a meeting with national security principals in the Obama administration's ongoing consideration of strategy for U.S. forces in southeast Asia.

The group will meet at 8 p.m. Monday, and will include Vice President Joe Biden, Secretary of State Hillary Rodham Clinton, Secretary of Defense Robert Gates, Joint Chiefs of Staff Chairman Adm. Mike Mullen, Gen. Stanley McChrystal and other top civilian and military leaders.

Obama said during an interview with NBC News last week that he would make a final decision about his strategy for Afghanistan in the coming weeks.

The president has been under pressure from Republicans in Congress to hasten his pace on a decision, which they say should back McChrystal's recommendation for as many as 40,000 new troops in the region.
