Senate Armed Services Committee Ranking Member John McCain, R-AZ, chats with reporters after a meeting on Afghanistan and Pakistan with US President Barack Obama October 6, 2009 at the White House in Washington, DC. Obama Tuesday sat down with senior lawmakers driving a raging debate on US Afghan strategy, as he works towards a decision on whether to send thousands more troops to war. Democratic and Republican leaders plus top members of key congressional committees met the president at the White House touting sharply conflicting visions of the next steps in the unpopular eight-year US military operation. Obama is methodically working through an internal policy review after US commander General Stanley McChrystal warned the war could be lost within a year without more troops, and reportedly asked for 40,000 more men.
