BARNSTABLE, Mass. -- John F. Kennedy's sister remains at a Massachusetts hospital with her family by her side.
Eunice Kennedy Shriver has suffered a series of strokes and was in critical condition at Cape Cod Hospital in Barnstable on Saturday.
Maria Shriver and Schwarzenegger were seen leaving the hospital Saturday.
The 88-year-old Shriver is the fifth of the nine Kennedy children. She's perhaps best known for her work to establish the Special Olympics.
That work was inspired, in part, by the struggles of her mentally disabled sister, Rosemary.
