The AP is reporting that Senator Ted Kennedy has been taken to the hospital from his home in Hyannis Port, MA.

Kennedy had surgery for a malignant brain tumor in June. He has been undergoing chemotherapy and radiation, and was strong enough last month for a surprise appearance at the Democratic National Convention in Denver.

UPDATE: Kennedy's office says in a statement that the senator had a mild seizure, possibly brought on by a change in medication. He will return home tonight.
