At this point, who cares what words Mr. Obama uses to describe his actions? He has done things that demand his sacking; after that, he can tell it to the judge.
Anything short of a nationally televised debate between representatives of the government agencies and the civil liberty/privacy groups is useless in my opinion.
Some of these things might be deceptions, but they also might just be caused by the fact that human language is imperfect and ambiguous and thus it is necessary to have really precise definitions for certain actions, especially when it comes to the law.
