Uh oh: Trump says he's willing to answer Mueller's questions under oath

Trump should reconsider, and not because I think he did anything wrong with respect to Russia. I don't. Actually, it's the fact that there clearly was no collusion between Trump and Russia that makes this so dangerous. When special counsels are coming up empty in the cases they were originally trying to make, they end up falling back on process crimes to justify the time and expense put into their investigation. And that usually means someone gets charged with perjury for what they told the special counsel in the course of the investigation, even if the underlying alleged crime is never found to have happened. That's how Patrick Fitzgerald got Scooter Libby, and it looks like it's how Mueller hopes to get Trump.
