Senator’s Daughter Dies at 36

Virginia Sen. Mark Warner is facing an unimaginable personal tragedy after announcing that his eldest daughter, Madison, has died at the age of 36. In a heartbreaking statement shared Monday, April 20, Warner and his wife, Lisa Collis, said their “beloved daughter” passed away after a decades-long battle with juvenile diabetes and other serious health issues.

The couple described Madison as a source of love and laughter whose loss has left an “immeasurable void” in their lives. They also asked for privacy as they grieve, turning what is usually a public life in politics into a deeply painful and personal moment for one of Virginia’s most prominent Democratic families.

Madison was the oldest of Warner and Collis’ three daughters and had been part of the family’s public journey since the early days of Warner’s political rise. Long before he became a nationally known senator, Warner was building his career in Virginia politics, later serving as governor before winning his Senate seat in 2008. Over the years, his family was often by his side through campaign stops, election nights, and some of the biggest turning points in his career.

But Madison’s health struggles were never far from the story. Warner had previously spoken publicly about how deeply juvenile diabetes affected his family, using those experiences to push for stronger protections for people with preexisting conditions and to call out the crushing cost of insulin in America. In one especially emotional moment, he said stories about young adults with Type 1 diabetes losing coverage broke his heart as a father.

The loss arrives at a major political moment for Warner. Just months ago, in December 2025, the longtime Democratic senator announced he would seek reelection in 2026, framing his campaign around economic recovery and the growing impact of artificial intelligence on workers and families. For now, though, politics has clearly given way to grief.

For many Democrats and Virginians who have watched Warner’s long career, this is not just another headline out of Washington. It is a devastating reminder that behind the speeches, policy fights, and campaign plans, there is a family now mourning the loss of a daughter who fought health battles for most of her life.
