Madison Warner, the eldest daughter of U.S. Senator Mark Warner of Virginia, has died at age 36 following a prolonged battle with juvenile diabetes and other health complications, the senator's office announced Monday.

The Democratic senator's office stated that Madison had fought a "decades-long battle with juvenile diabetes and other health issues" before her death. No additional details about the circumstances or timing of her death were immediately provided.

Juvenile diabetes, also known as Type 1 diabetes, is an autoimmune condition that typically develops in childhood or adolescence. The disease requires lifelong management through insulin therapy and can lead to serious complications affecting the heart, kidneys, eyes, and other organs if not properly controlled.

Senator Warner, who has served Virginia in the U.S. Senate since 2009, has not yet released a public statement regarding his daughter's death. The senator's office has requested privacy for the family during this time.
