Eunice Shriver, the 88-year-old sister of Sen. Ted Kennedy, is in intensive care in a Massachusetts hospital, the Cape Cod Times reports. The Special Olympics founder has been in the hospital for a week and is in critical but stable condition. Her family, including daughter Maria Shriver and son-in-law Arnold Schwarzenegger, is by her side. “The family is grateful for the prayers of her many friends,” a Special Olympics spokesman says.
