Kara Kennedy, the eldest daughter of the late senator Ted Kennedy, has passed away.

The television producer suffered a heart attack on Friday immediately following a workout at a Washington D.C.-area gym, the New York Times confirms. She was just 51 years old.

Her brother Patrick J. Kennedy, a former Rhode Island congressman, told The Associated Press, "She's with Dad."

Ted Kennedy, the outspoken former Massachusetts politician, died of brain cancer in August 2009, just two weeks after Kara accepted the Presidential Medal of Freedom from President Barack Obama on her father's behalf.

Kara was diagnosed with lung cancer in 2002, which then went into remission. "[It] took quite a toll on her and weakened her physically," Patrick told The AP.

She leaves leaves behind her husband, Michael Allen, and their two teenage children, Max and Grace.
