Under our system of government, certain officials have certain powers. The Federal law enforcement authority (the DOJ) cannot prosecute their senior-most boss. That would be like the fox guarding the hen house. It’s a bad idea, and anyone who laments that it isn’t being done doesn’t understand our Constitution.

But no one is above the law. The President can fire any senior DOJ official who should be prosecuted. The Congress can remove any President, including one who conspires with the AG and refuses to fire him, or pardons him. And an ex-President can be prosecuted. If Congress doesn’t impeach and convict a President who deserves it, the people can vote out the Congress. Everyone is accountable, if everyone, indeed, if anyone, including the electorate, does their job. So, if the system fails, it fails because the voters don’t give a crap about the things Ms. Holland (and I) care about.

Mr. Mueller found and reported facts (not conclusions of law about those facts) that can reasonably be regarded by Congress and the public as criminal obstruction and punished accordingly, i.e., through the Constitutional mechanisms established for that purpose. In short, he did his job. Now, it’s up to Congress and/or the voters to do theirs.
