President Joe Biden writes "I was heartbroken to hear about the loss of your daughter, Harmony. As we both know, and as I told you when I saw you in Philadelphia last year, there are no words that can ease the pain of losing a child a part of your soul. Jill and I are standing with you and your family during this difficult time," wrote the President. "We both know how hard loss is," he continued. "It leaves a hole in your heart that never fully heals. But as someone shared with me long ago, it's important to find purpose as you move forward. I hope you are able to continue turning your pain into purpose. I know you know this, but Harmony and Jihad will always be with you. You've heard me say this before, and I truly mean it I promise that the day will come when the memory of Harmony brings a smile to your lips before it brings a tear to your eye. My prayer for you and your family is that this day comes sooner rather than later. Biden has also lost two children: his firstborn daughter Christina in a car accident, and his son Beau to cancer.
