Madison Warner was 36.

“We are heartbroken beyond words by the passing of our beloved daughter … after a decades-long battle with juvenile diabetes and other health issues,” according to a statement by the senior senator from Virginia and wife Lisa Collins.

“She filled our lives with love and laughter, and her absence leaves an immeasurable void. We are grateful for the loving support of friends and family during this difficult time and ask for privacy as we navigate this profound loss.”

Warner is in the midst of a re-election campaign, seeking the Democrat’s fourth term in office representing Old Dominion.

Condolences from across the political spectrum began pouring in shortly after the announcement of his daughter’s death.

Vice President JD Vance, a Republican who is frequently at odds with Warner on policy, posted that his family was thinking of the Warners.

“Our prayers are with Sen. Warner, his daughter, and their whole family,” Vance posted to X. “What a terrible loss at such a young age. May God comfort them.”

U.S. Sen. Raphael Warnock, D-Ga., said in a statement, “Mark, I’m praying for you and your family as you grieve this unimaginable loss.”

“Even in this grief, God is near to the brokenhearted, holding you in ways we cannot always see or feel right now,” Warnock wrote.
