U.S. Secretary of Defense Robert Gates (L) walks with U.S. Army Lt. General Kenneth Hunzeker after arriving at Baghdad International Airport December 10, 2009. Secretary Gates is in Iraq following a two-day-trip to Afghanistan one week after U.S. President Barack Obama announced that he will send an additional 30,000 troops to Afghanistan. U.S. Secretary of State Hillary Clinton and Gates will face questioning next week from lawmakers who control government spending about the cost of the Obama administration's surge of troops into Afghanistan, congressional aides said on Thursday.
