 Tony, thank you so much. Dr. Jim Sweetland, an ER physician, was at the scene of last night's rally when he witnessed the shooting. He said he administered aid to a spectator who was gravely hurt. Dr. Sweetland, thank you so much for joining us this morning. You're very welcome. Can you just relay your experience of what happened to you, and have you ever been in a live kind of situation like this, obviously in the ER, but I mean out in the field with this kind of thing happening?
