Ethel Kennedy, a social justice advocate and the widow of late U.S. Attorney General Robert F. Kennedy, is recovering in a hospital after suffering a stroke last week, her grandson said in a statement. Former Rep. Joe Kennedy III (D-Mass.) posted on the social platform X on Tuesday that his grandmother had suffered a stroke and was taken to a hospital where she is receiving treatment and is "comfortable." "Unfortunately, on Thursday morning she suffered a stroke in her sleep. She was brought to an area hospital, where she is now receiving treatment," he wrote in the post. "She is comfortable, she is getting the best care possible, and she is surrounded by family," he added in the post. Ethel Kennedy, 96, is former President John F. Kennedy's sister-in-law and mother to 11 children, including former independent presidential candidate Robert F. Kennedy Jr. In the statement, Joe Kennedy asked for privacy at this time. "Please keep her in your thoughts and prayers. We ask that you respect our family's privacy at this time," he wrote in the post.
