Sen. Ted Kennedy, the last of three brothers who changed the American political scene in the 1960s, had "a good night's sleep" at a Massachusetts hospital, after he suffered a seizure Saturday while at the Kennedy family compound in Hyannisport, Mass.
Kennedy, age 76, is being evaluated by doctors to determine the cause of the seizure, but results are not expected until Monday or Tuesday, a Kennedy source said.
Kennedy, D-Mass., who has served in the Senate since 1962, was taken by ambulance to a Cape Cod hospital in the morning and later flown to Massachusetts General Hospital in Boston by helicopter.
"Preliminary tests have determined that he has not suffered a stroke and is not in any immediate danger," Kennedy's physician Dr. Larry Ronan said Saturday evening. "He's resting comfortably, and watching the Red Sox game with his family.
Kennedy's wife, Victoria, was with him at the hospital, Kennedy family spokeswoman Stephanie Cutter said. Several other members of the senator's family visited him at the hospital, including his three children, Kara, Edward Jr. and Rep. Patrick Kennedy, Democrat of Rhode Island, niece Caroline Kennedy and nephew, former Rep. Joseph P. Kennedy, II.
He spent much of the afternoon watching sports on television: first the Boston Red Sox game, then the Boston Celtics' playoff game against the Cleveland Cavaliers. Kennedy went to Cape Cod Hospital Saturday "after feeling ill at his home" in Hyannisport, Cutter said.
"We got a 911 call at 8:19 a.m. this morning for a request for an ambulance," Lt. Bill Rex, a spokesperson for Hyannisport Fire and Rescue, confirmed to ABC News, Saturday. "We transferred one male to Cape Cod Hospital in Hyannis."
Kennedy's doctors in Boston were contacted, and it was decided he should be taken to Massachusetts General Hospital for further testing.
Rex also confirmed that an ambulance was later used to transport Kennedy to an airlift from Barnstable Municipal Airport for an emergency flight to Boston.
Kennedy is no stranger to brushes with death.
In 1964, only a year after the assassination of President John F. Kennedy, the newly elected senator and Sen. Birch Bayh, D-Ind., were nearly killed in a horrific plane crash that claimed the life of the pilot and one of Kennedy's aides.
Kennedy suffered two fractured ribs and three broken vertebrae in his back, an injury that would cause him a lifetime of back pain.
In October 2007, Kennedy had surgery to repair blockage in the left carotid artery in the neck believed to be connected to the injuries he suffered in the crash more than 40 years ago.
In July of 1969, a year after the assassination of his brother, Sen. Robert F. Kennedy, the senator once again escaped a fatal crash.
After a night of partying, Kennedy drove his mother's 1967 Oldsmobile over a wooden bridge on Chappaquiddick, an island off of Martha's Vineyard, killing passenger Mary Jo Kopechne.
Questions surrounding why Kennedy survived while Kopechne drowned have haunted the senator ever since.
He was convicted of leaving the scene of an accident and lost his license for a year, but the Kopechne family never sued the Kennedys or the senator for his role in the incident.
In more recent years, Kennedy was traveling with the late Sen. Paul Wellstone, D-Minn., on the day Wellstone's campaign plane crashed just outside of Eveleth, Minn.
