“When I announced my diagnosis six months ago, I promised transparency. After grueling treatments, we’ve learned that the cancer, while initially beaten back, has now returned. I’ll do everything possible to continue to represent you and thank you for your grace,” he said in a statement at the time.

Connolly has served as a congressman from Virginia’s 11th district, which includes parts of northern Virginia, since 2009. Before that, he served on the Fairfax County Board of Supervisors for 14 years.

The statement from Connolly’s family on Wednesday added: “Gerry lived his life to give back to others and make our community better. He looked out for the disadvantaged and voiceless. He always stood up for what is right and just.”

“His absence will leave a hole in our hearts, but we are proud that his life’s work will endure for future generations. We thank you for your love of Gerry, and know he loved you all so much.”
