Warner and his wife Lisa Collis said in a news release that Madison died after a decades-long battle with juvenile diabetes and other health issues. According to the statement, the couple described their daughter as having filled their lives with love and laughter, and her absence leaves an immeasurable void. They also expressed gratitude for the loving support of friends and family during this difficult time and asked for privacy as they navigate this profound loss.
The exact cause of Madison's death and the specific other health issues she faced have not been disclosed. Warner was first elected to the Senate in 2008 and has been reelected twice since then, in 2014 and 2020. He is up for reelection later this year.
Warner and his wife live just outside of Washington, DC, in Alexandria, Virginia, and have two other daughters, Gillian and Eliza. How the family is coping with the loss beyond the public statement remains private. Type 1 diabetes is an incurable genetic condition, although experimental therapies are in development for the disease.
The experimental therapies mentioned as being in development were not specified in the announcement.
