This is Obama bureaucracy lying again. U.S. passports or a green card (legal residency) have bar codes and RF tags with your personal information embedded in them. They would have been machined scanned on entry into the U.S. Are these libtards telling us he did not have to used a passport or credit cart to print his boarding pass and get his bags checked in?
Besides, the Russian are neither incompetent nor stupid. They would have passed the data they had on him from the visa he used to get access to their territories.
