One thing is clear, however – Petraeus is a an American Hero. Reports show that his indiscretions were evident to the FBI in October. The Administration was terrified of what he might say to Congressional investigation concerning Benghazi, so they tried to blackmail him into saying what they wanted him to. He refused to lie, and cut their leverage on him by outing himself on the affair. Now, if subpoenaed to testify, he can tell the truth with a clear conscience, which will be an indictment against the President. Unfortunately, it will have no effect, because even if it rises to the level of an impeachable offense, the Senate will never convict Obama in a million years.
