The family of U.S. Senator Mark Warner (D-Va.) is mourning the loss of their eldest daughter, Madison Warner, who passed away today, Monday, April 20, 2026, at the age of 36.

Her passing was announced in a heartfelt statement by Senator Warner and his wife, former Virginia First Lady Lisa Collis.

A Life of Strength and Privacy
Madison’s passing follows a brave, decades-long battle with health challenges that she and her family managed with great privacy.

Health Battle: She suffered from juvenile diabetes (Type 1) and other related health issues for most of her life. While Senator Warner has often been a vocal advocate for diabetes research and insulin affordability in the Senate, the specific identity of which of his daughters was fighting the disease was kept private until now.

Family Impact: In their statement, her parents described her as a source of “love and laughter” whose absence leaves an “immeasurable void.”

Personal History: Madison was the oldest of three daughters. Senator Warner famously cited a college tour with Madison in 2006 as a primary reason he decided not to seek the 2008 Democratic presidential nomination, choosing instead to prioritize “real life” and these irreplaceable family moments.
