Should Democrats demand that Donald Trump testify under oath?

9. I would have to imagine the assertion of two clearly mutually-exclusive ... uh ... things

while under oath would constitute de facto perjury ... and that Trump would certainly do exactly that if questioned by a skilled prosecutor, like you say.

Seems well worth it to me to at least request him to show up and testify, and pillory him for not doing so.

Make him claim 'his 5th amendment right'.

And then point out he HAS NO 5th Amendment right because this isn't a criminal case. It's a JOB INTERVIEW, basically.
