CNN is reporting that a Senator has collapsed at the Congressional Luncheon celebrating the inauguration of President Obama. It may have been Sen. Robert Byrd, but that is not yet confirmed. Other reports suggest that it was Sen. Ted Kennedy. No one seems to be sure which senator it was. We’ll update when we know more. Update: NBC says that Sen. Robert Byrd (D-W. Virginia) suffered a medical emergency and was taken to a hospital. But now President Obama is talking about Ted Kennedy having had an emergency. It seems as though maybe both men collapsed … ? Update II: Politico reports both men were taken out of the luncheon under medical supervision, Byrd because he was having trouble eating, Kennedy after having gone into apparent convulsions. Update III: The Associated Press now says that Kennedy is awake and answering questions at Washington Hospital Center. The AP report also quotes Byrd staffers saying that the West Virginia senator left the luncheon for reasons that were not health-related. Here’s what Claire McCaskill (D-Mo.) sent out via her Twitter feed at about 3:15 p.m.: “My friend Ted Kennedy just was taken away in an ambulance. Convulsions. Please pray for the Lion of the Senate.”
