This is absolute nonsense. The US president, wrapping himself in the role of commander in chief, does just about anything he wants if it's even loosely connected to war or security, with or without congressional approval. Surveillance. Torture. Black sites. Assassination. Drone murders. Infinite detention. If he wanted Gitmo closed, he could close it. Congress won't give him the budget? Fine, he could order the closing as a military operation. He doesn't want to take the political heat. I voted for him (2008), but he is without testicular fortitude on this issue.
