Here is a video report on President Obama's surprise trip to Afghanistan today, where he met with Afghan President Hamid Karzai, and spoke to a group of 2,000 U.S. Troops. Obama thanked the troops, and told them "everyone" back home is behind them.
Obama was on the ground for six hours in Afghanistan, and is now on the way back to the U.S. This was Obama's first trip to Afghanistan as President.
