Sen. Edward Kennedy (D-Mass.) was taken out of President Obama's inaugural luncheon by medics after he suffered a seizure.
"After testing, we believe the incident was brought on by simple fatigue," Dr Edward Aulisi of Washington Hospital Center said in a statement issued through Kennedy's office. "Senator Kennedy is awake, talking with family and friends, and feeling well."
The 76-year-old Senator was diagnosed with a malignant brain tumor in May 2008, after experiencing a seizure at his family's compound in Hyannis Port on Cape Cod, Mass.
"He'll be OK, the good news is, he's going to be fine -- that's the best news," Sennator Chris Dodd (D-Conn.) told reporters, adding Kennedy had said: "'I'll be OK, I'll see you later.'"
Republican Senator Orrin Hatch said that after the scare, Kennedy's condition had gradually improved as he was taken to the ambulance.
"I'm not a doctor, but it looked like a seizure, and it was painful to him but as he gradually was able to calm down, as he got into the ambulance, he kind of looked over at me and smiled, that old wry smile that I know things are going to be all right.
"I know that, when I was out of the room, concern was expressed about Teddy," said newly sworn-in President Obama, shortly after the Senators were taken away.
"He was there when the Voting Rights Act passed [and] along with John Lewis, was a warrior for justice. And so, I would be lying to you if I did not say that right now, a part of me is with him, and I think that's true for all of us. This is a joyous time, but it is also a sobering time, and my prayers are with him and his family ..."
An earlier report that Sen. Robert Byrd (D-W.Va) had also fallen ill during the luncheon was later denied by his office, though aides noted the 91-year-old is very concerned for Sen. Kennedy's health.
