Editor's note: The President's live address has ended. But we'll leave this post active for the comment thread which passed 400 comments before the live event even began. We'll be posting the recorded version of the President's remarks shortly.
Update: Here are the President's complete remarks:
The President will address the nation from the White House at 10:30 -- but right now the subject is unknown.
The announcement came abruptly -- after the White House had declared that "no other news would be coming for the remainder of the day."
We'll update this post over as we get more information and post a live stream here if it is available. For now post any speculation to comments.
Update: The pre-speech indications at 10:40 point to reports that Osama bin Laden is dead.
Update: Fox News is reporting that bin Laden was killed over a week ago by a U.S. bomb and the U.S. was waiting for DNA confirmation.
Update: I'm posting two live streams in case there are any technical issues -- the MSNBC stream is first, then the official White House stream which is auto playing. That's FYI as you choose which to watch.
Update: The President's speech is underway and he is confirming the death of Osama bin Laden. But early reports about a bomb operation in Afghanistan may have been incorrect. The operation was on the ground inside Pakistan. Look for new posts shortly.
