The author supports Flynn, and avers that he is the first Trump insider they brought down. I wonder about that. It seems from what we've read that Flynn's handling of the "contact with Russia" claims was sloppy. Add to that, one of his appointees had to be removed from their position. I'm sure there's more to the story than we've been made aware of.
Flynn brought himself down with the Pence thing. If it wasn’t for that he would probably have his job still.
