Was tuned in and watching live. President abrubtly taken away from podium and escorted out of the room. Something going on outside. Not sure where this speech was given from, do not think from the White House. Not sure.
I only heard a brief minute or two and then he was taken away. Camera people all flocked to windows to film something outside and chat room was abuzz and the feed ended.
