With a memo that the President approved the release of, he has abdicated his responsibilities as Commander and Chief to protect the American people by protecting our intelligence sources and the rest. It's appalling, it's a misrepresentation, it isn't even a release of intelligence material, it's a release of a distortion of it.
What is its purpose? Its purpose is of course to thwart the investigation, the Mueller investigation. This is unprecedented to the nth degree, it isn't like any release of intelligence. It's a release of distortion without showing the facts under it now.
