BOSTON — Sen. Edward Kennedy is undergoing further evaluation at a Boston hospital, two days after the 76-year-old Democrat suffered a seizure.

Kennedy's spokeswoman Stephanie Cutter says it is unclear when doctors will release information on Kennedy's condition or on the cause of his seizure Saturday.

Cutter said Monday the senator had a restful night at Massachusetts General Hospital. He spent Sunday watching sports and movies and visiting with family.

President Bush had been notified of Kennedy's health just before he went to a Saturday night dinner meeting with Palestinian President Mahmoud Abbas.

Cutter says Bush called Kennedy's wife, Vicki, on Monday to check on the senator's progress and asked her to take care of his friend.
