From a constitutional lawyer friend:

The Schumer thing, a question about a 1923 decision (Meyer v. Neb), is just silly. I had to go skim the case to remember what it was about. I had no idea when I saw the name. Yes, I had read it before, but not since law school. Whether a state can ban the teaching of German language classes under 1st A. You can be a Supreme Court justice without remembering what that case is about.
