Currently, roughly 68,000 U.S. troops remain in Afghanistan. In meetings on Friday, the two leaders discussed various plans to continue the transition in Afghanistan, as well as the size of a potential residual force that could remain in the country after the official end of the war.
The Obama-Karzai meeting is the pair's first since Obama's re-election in November. It also comes amid a shakeup in Obama's second-term defense team, as Obama has announced nominees to fill the Secretary of Defense, Secretary of State and CIA Director positions.
Two of those nominees — former Sen. Chuck Hagel for defense and Sen. John Kerry for state — could push for a faster withdrawal than what has been on the table.
