RICHMOND, Va. — U.S. Rep. Gerald “Gerry” Connolly, an outspoken Democrat who sought key reforms in the federal government while bringing transformational development to his populous Virginia district, died Wednesday. He was 75.

Connolly, who most recently held a prominent position as the ranking member of the House Oversight Committee, served in Congress for more than 16 years.

He died at home in the company of family members, his family said in a statement. Connolly announced in 2024 that he had esophageal cancer and said a few months later that he planned to retire from Congress.

A fixture of Virginia politics for three decades, Connolly was first elected to the Fairfax County Board of Supervisors in 1995. On the county board, he steered the transition of northern Virginia’s Tysons Corner from a traffic-heavy mall area to a downtown business hub.

In 2003, Connolly was elected board chairman, and he continued pushing for transportation investment that had been debated among officials for decades. Connolly sought billions in state and federal dollars to develop the regional rail system’s Silver Line connecting the national capital region to Tysons Corner.

Connolly’s dream was realized with the Silver Line’s opening in 2014, and eight years later, the rail line was extended an extra 11 miles (18 kilometers) to reach Dulles International Airport.

As the extension opened in 2022, Connolly said: “Doing big things is difficult – the world is filled with naysayers.”

Connolly’s local government experience launched his congressional career. He was elected in 2008 after flipping an open Republican-held seat by nearly 42,000 votes. In his victory speech, Connolly said he would use his position to ensure the federal bureaucracy is “a responsive, accountable instrument for the people we serve.”

“If we insist the government must work for all of our citizens again, we cannot fail,” Connolly said.

The spirited and at times bullheaded Fairfax Democrat became known for his voluble nature and willingness to engage in spirited debates. In one hearing, he accused Republicans of engaging in a witch hunt against the IRS, asking a witness if they ever read Arthur Miller’s “The Crucible.”

Connolly got his first taste of Congress while working as a staffer for the Senate Committee on Foreign Relations in the 1980s. Decades later, Connolly became a member of the House Committee on Foreign Affairs.

He also served as a member of the House Oversight Committee and led Democrats on subcommittees on government innovation and information technology.

Connolly cosponsored the 2010 Telework Enhancement Act, which requires federal agencies to allow a portion of their employees to telework at least one day a week. In 2014, he cosponsored another bill that reformed federal IT management and has since saved the government billions of dollars, according to the Government Accountability Office.

He also closely followed the financial burden of the slowing U.S. Postal Service, becoming a prominent voice accusing President Donald Trump and former Postmaster General Louis DeJoy of seeking to winnow the postal service to suppress mail-in ballots during the 2020 presidential election.

Connolly reached a new milestone late last year as he was chosen ranking member of the House Oversight Committee. He defeated Democratic Rep. Alexandria Ocasio-Cortez for the position. The victory came shortly after Connolly announced late last year that he had been diagnosed with esophageal cancer and would undergo chemotherapy and immunotherapy.

As ranking member, Connolly called on inspectors general to investigate the Department of Government Efficiency. He and other Democrats also introduced a pair of resolutions demanding the Trump administration turn over documents and information about billionaire adviser Elon Musk’s potential conflicts of interest and the firings of federal workers.

He said in late April that after “grueling treatments,” he learned that the cancer had returned and that he decided to step down from his post on the committee and would not seek reelection.

“With no rancor and a full heart, I move into this final chapter full of pride in what we’ve accomplished together over 30 years,” he said.
