Biden makes unannounced stop in Baghdad

Vice President Joe Biden made an unannounced stop in Baghdad on Tuesday to meet with Iraqi leaders and thank U.S. troops before they withdraw from the region at the end of the year. The White House said planning for the vice president's trip was kept secret for security reasons.

While in Iraq, Biden will co-chair a meeting of the U.S.-Iraq Higher Coordinating Committee, meet with Prime Minister Nouri al-Maliki, President Jalal Talabani, Speaker Osama al-Nujaifi, and other political leaders.

Biden will resume his scheduled trip to Greece and Turkey after his stop in Baghdad. It is his eighth trip to Iraq since being elected vice president.
