Something really extraordinary has happened in the past 15 hours, and the Washington Post is at the center of it. But contrary to what you're being led to believe, the real scandal here is not President Trump supposedly revealing classified information to the Russians. That may or may not have happened, although I tend to doubt it, and I'm all but certain it didn't happen in the way the Post claims.
The real story here is the Post broke new ground in irresponsible reporting with the way it put together this story. To understand this, you need to know some of the basics of what journalists are taught to do. That will give you context for just how badly the Post strayed from these essential standards of the profession.
