Biden visits Iraq for July 4th celebrations

US Vice President Joe Biden made a surprise visit to Baghdad on Saturday for the Fourth of July holiday in the midst of a political deadlock nearly four months after Iraq's national election.
Biden arrived at a time when many question whether the US policy in Iraq is adrift. They say they worry that with a shift of attention toward America's other war, Afghanistan, and so much attention on the planned withdrawal of US troops, the United States is focused only on its exit and not the success of a still very shaky democracy in Iraq.
This was Biden's fourth trip to Iraq as vice president. President Obama has visited once since he became commander in chief.
