William C. Miller Jr., a seasoned lobbyist and prominent political strategist, has been appointed Senior Vice President of the Business Roundtable (BRT), a collective representing CEOs of America’s leading corporations. The announcement, set for Friday, marks a strategic move for BRT as it seeks to expand its influence in Washington and shape the future of U.S. policy.
Miller will oversee BRT’s outreach efforts to Capitol Hill and the administration, playing a pivotal role in aligning corporate interests with public policy. The organization, under the leadership of President John Engler, represents companies generating over $6 trillion in annual revenue and employing more than 14 million Americans.
Miller joins BRT from the Brunswick Group, a global consulting firm he joined last November after a 12-year tenure at the U.S. Chamber of Commerce. At the Chamber, he served as Political Director and Senior Vice President for Political Affairs and Federal Relations, spearheading initiatives that expanded grassroots and political advocacy.
“Bill Miller is a hardworking, enthusiastic leader,” said Thomas J. Donohue, President and CEO of the U.S. Chamber of Commerce. “During his time at the Chamber, Bill significantly expanded our political and grassroots efforts. He knows Washington, knows the key players, and is a valuable asset to the Business Roundtable.”
Engler emphasized Miller’s role in bolstering the BRT’s policy influence. “We need more than an opinion,” Engler said. “We must offer actionable solutions—whether it’s creating a competitive tax code or addressing energy policy—to maintain America’s edge in the global market. The CEO voice will be critical in shaping debates over infrastructure, tax reform, and entitlement reform in what promises to be a high-stakes legislative session.”
Before his tenure at the Chamber, Miller served as Chief of Staff to former Representative Constance A. Morella of Maryland, beginning in 1994. He holds a Bachelor’s degree from the University of Maryland and a law degree from American University.
The Business Roundtable’s influence is underscored by its members, whose companies account for nearly one-third of the total value of the U.S. stock market and nearly half of private-sector research and development spending. With Miller’s leadership, the BRT aims to strengthen its policy initiatives and continue advocating for sustainable economic growth and innovation.
As Miller steps into his new role, he brings decades of experience and a deep understanding of Washington’s political landscape, making him a valuable addition to the BRT during a critical time for the nation’s economy and infrastructure.
