Sen. Edward Kennedy was rushed to Cape Cod Hospital in Massachusetts Saturday morning, a well-informed, prominent Democratic source in that state told CNN.
The source said the 76-year-old senator had "symptoms of a stroke."
Kennedy was taken to the hospital around 8 or 9 a.m. from the Kennedy family compound in Hyannis, according to the source. The source said the senator would be transferred to Massachusetts General Hospital in Boston.
That hospital said it had no information on Kennedy.
