Questions surround the release of Sgt. Bowe Bergdahl

For five years, Bowe Bergdahl was America's only prisoner of war in Afghanistan. Now that he has been released, there are serious practical, political and constitutional questions being raised.

We know Bergdahl left his base, but did he abandon his unit? Some who served with him are questioning his actions and intentions that night. Some fellow soldiers are even calling Bergdahl a traitor. Intensifying that anger is the loss of six American soldiers, killed while there was an intense search for him.

Some lawmakers are questioning whether the Obama administration broke the law by releasing five Gitmo detainees without the approval of Congress? Does this deal signal the Obama administration is willing to negotiate with terrorists?

Sergeant Bergdahl will be heading home. For now, he is at the U.S. military hospital in Landstuhl, Germany. For Berghdal, the process of reintegration is just beginning. Those who stood vigil for five years are still waiting to embrace him again.
