It has been very obvious that the US government has been slow dripping information to the public for several years now. I think this is the next step in that process. Trump's daughter in law made a comment recently that made me think this announcement was imminent - sort of reminded me of Miller's wife making that Greenland post. There are a lot of UFO "whistleblowers", all of whom are conveniently from the intelligence community, and seems to be treated far better than other "whistleblowers". So there's a long term angle there from the US government. Who knows what that is. And whatever we are permitted to learn, it'll be what serves the US government. I very much believe there is something happening that defies prosaic explanation, but I doubt we'll learn anything too crazy, and if we do, I'll have no idea if we can trust it.
