Larry King's sons reacted to their father's death in an emotional statement on social media.

Larry King, Jr., Chance King, and Cannon King took to Facebook to pen a lengthy note about how much their father meant to them.

"We are heartbroken over our father's death, and together with our extended family mourn his passing. The world knew Larry King as a great broadcaster and interviewer, but to us he was 'dad.' He was the man who lovingly obsessed over our daily schedules and our well-being, and who took such immense pride in our accomplishments -- large, small, or imagined. And, through it all, we knew without a doubt in the world that he loved us more than life itself. He was an amazing father, and he was fiercely loyal to those lucky enough to call him a friend. We will miss him every single day of our lives," the brother said. 

They also thanked fans for the "outpouring of love" and tributes to King's "remarkable career." They asked that in lieu of flowers, please consider donations to the American Heart Association or the Beverly Hills Fire Department EMS.
