I don’t believe even a single word that they have said or are saying about Flynn. They have not yet said what it is he is supposed to have lied about, not to Pence, not to the FBI. And that, by itself, is weird.
Of course, we don’t know even yet what happened in Vegas, about the guy who shot 500 people... you know that five minutes after they had his phone, laptop, search history, and bank records they knew exactly what it was about. But they are not talking.
Trump said the General lied to Pence and the FBI. What additional evidence do you need that he lied?
