Normally, I am grateful for the First Amendment and the absence of sedition laws. Right now, part of me wishes that these statements were at least probable cause for an exhaustive investigation into Bannon's financial transactions.

That's an incredibly dangerous can of worms to open, but at the same time it's fairly clear that these people are dedicated to getting their preferred policy outcomes at any price up to and including the destruction of the Constitution.
