GAINESVILLE, Va. – Bob Weir, the Gainesville District Supervisor on the Prince William County Board of Supervisors and a longtime fixture in local politics, died July 20, 2025, after a short but aggressive battle with colon cancer. He was 62.
Weir was known across Prince William County not just for his deep policy knowledge and procedural rigor, but for his fiery style, unfiltered commentary, and devotion to public service. State Senator Danica Roem, who covered Weir during her years as a journalist before entering politics, described him as “a curmudgeon in the most loving sense of the word.”
