Biden arrives in Iraq

Vice President Joe Biden today made a surprise visit to Baghdad, Iraq -- in advance of the full American troop withdrawal that is expected to happen next month. This is Biden’s eighth trip to Iraq since becoming vice president. 

According to the White House, while in Iraq, Biden will speak at “an event to commemorate the sacrifices and accomplishments of U.S. and Iraqi troops."

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

Last month President Obama confirmed that the United States would remove all troops from Iraq by the end of the year, keeping with a bilateral agreement that was signed by President George W. Bush before he left office.

NBC's Ann Curry reports from Iraq where Vice President Joe Biden has made an unannounced visit, ahead of the withdrawal of U.S. troops from the country.
