New York (CNN Business) Walmart CEO Doug McMillon on Thursday was named the incoming chairman of Business Roundtable, the prominent group of 192 chief executives representing corporate America's interests in Washington.

McMillon, a Walmart lifer who became the company's chief executive in 2014, will serve a two-year term as Business Roundtable's leader beginning in January. McMillon will take over for JPMorgan CEO Jaime Dimon, who has led the group since 2017.

Business Roundtable counts some of America's largest companies among its ranks. The powerful group lobbies policymakers and looks after corporate America's public image.

McMillon, 52, said in the coming months "there will be extensive conversations about America's future and the role business plays in shaping it," nodding to the 2020 election. He committed to "keeping Business Roundtable CEOs at the forefront of constructive public policy debates."
