Has anything about this officially been announced? Or just leaks from anonymous sources?
I think charging Comey with leaking his own memos right now would be unwise, but oppose announcing a non-prosecution decision, which might foreclose options later. Hold fire now, and wait until all the FISA, overall coup, and other issues are on the table, including Comey’s lead role in them. Comey’s memos, leaks, lies, and plots look a lot worse in context than as a stand-alone.
Looking back through posts, the Fox News story indicates it’s from sources working the case. Not an official announcement.
