Lied about what exactly? That he talked to the Russians? He was talking to the Russians before Trump and Pence were elected.
This is a political witch hunt, and the socialist-democrats scored a hit.
Now is the time for President Trump to crack down on these leaks, and start weeding out the leftist obama holdouts and sympathizers.
Wholesale shitcanning of government intelligence and executive branch employees is in order.
They serve at the leisure of the President, and if he says that they go, they. are. gone.
What exactly seems to be the problem. Here is a report by Krauthammer about the complexities: http://insider.foxnews.com/2017/02/16/krauthammer-trump-russia-flynn-story-why-lie-vice-president-pence
Key quotes from article: “the key question from the story involving former National Security Adviser Michael Flynn and the Russian ambassador is why the retired general failed to tell Vice President Pence the truth about their discussion.” and “Reports said Flynn was not truthful about the conversation when discussing it with Pence, who went on news programs with the faulty information he was told.”
So the key seems to be that Flynn failed to give Pence correct information which then caused Pence embarrassment.
