Ethel Kennedy, the widow of Robert F. Kennedy, has died at the age of 96, her family announced Thursday.

Kennedy had been hospitalized earlier this month after suffering a stroke on Oct. 3. 

Joe Kennedy III, a former congressman, announced Ethel's passing in a post on social media.

"It is with our hearts full of love that we announce the passing of our amazing grandmother, Ethel Kennedy. She died this morning from complications related to a stroke suffered last week. Along with a lifetime's work in social justice and human rights, our mother leaves behind nine children, 34 grandchildren, and 24 great-grandchildren, along with numerous nieces and nephews, all of whom love her dearly," Kennedy wrote.

"She was a devout Catholic and a daily communicant, and we are comforted in knowing she is reunited with the love of her life, our father, Robert F. Kennedy; her children David and Michael; her daughter-in-law Mary; her grandchildren Maeve and Saoirse; and her great-grandchildren Gideon and Josie," he added. "Please keep her in your hearts and prayers."

Ethel was the sister-in-law of former President John F. Kennedy. She founded the Robert F. Kennedy Human Rights organization in 1968 after her husband was assassinated in June of that year.

Ethel's death comes at a time of division within the Kennedy family, with Robert F. Kennedy, Jr. endorsing former President Trump to the anger of his siblings and other family members, who support Vice President Kamala Harris.

"You know, my family is at the center of the Democratic Party. I have members of my family that are working for the Biden administration. Biden has a bust of my father behind him at the Oval Office, and he's been a family friend for many years," Kennedy told Fox News in August.

"My family is — I understand that they're troubled by my decisions. I love my family. I feel like we were raised in a milieu where we were encouraged to debate each other and debate ferociously and passionately about things and still love each other," he added. "They're free to take their positions on these issues. There are many, many members of my family working at my campaign and who are supporting me."
