President Obama today welcomed congressional leaders to the White House to discuss his war strategy in Afghanistan. Republicans made it clear that they back General Stanley McChrystal and his counter-insurgency strategy — for which he wants 40,000 more troops. Democrats instead are pushing not for higher troops levels, but for specialized operations and missile strikes. The meeting came on the eve of the eight-year anniversary of the war in Afghanistan — and after a particularly bloody weekend firefight that killed eight soldiers and injured two dozen. So tonight, we ask you: What should the president do? Tell us what you think. You can follow "Nightline" anytime on Twitter: http://twitter.com/Nightline.
