I suppose you and Senator Warren have different definitions for unauthorized.
Here's a question for you to think about: Why do they reverse some claims but not others?

The scare quotes imply that they are the ones saying the case isn't very strong, so I'm not quibbling with them, I'm trying to interpret them.
