Kara Kennedy dies at 51

Kara Kennedy, the eldest daughter of former Senator Ted Kennedy, and sister of Patrick Kennedy, died suddenly on Friday, the family confirms. She was 51. She was working out in a Washington D.C.-area gym at the time, the Associated Press reports. "She's with dad," Patrick Kennedy said. Their father died in 2009 at age 77 after battling a brain tumor. Kara, who helped work on her father's senatorial campaign, was also a cancer survivor. In 2003, she had a malignant tumor removed from her lungs. According to her brother Patrick, the cancer treatment "took quite a toll on her and weakened her physically. Her heart gave out." Kara is survived by her husband Michael Allen and two teenage children.
