Aaron C. Cummings

Aaron has years of high-level experience on Capitol Hill. He’s the former Chief of Staff to U.S. Senator Chuck Grassley (R-IA), the longest serving Republican Senator in history, and current President Pro Tempore-emeritus of the Senate. As Senator Grassley’s Chief of Staff, Aaron worked closely with other members of Republican Senate Leadership and their senior staff to advance the priorities of the Republican Caucus and to set the agenda for the Senate. Aaron also advised Senator Grassley during his tenure as the Chairman of the powerful Judiciary and Finance Committees, the top Republican of the Committee on Budget, and as a senior member of the Senate Committee on Agriculture. During his tenure as a Chief Counsel on the Senate Judiciary committee, Aaron advised Senator Grassley on a host of policy and constitutional issues, including Supreme Court nominations, and was the lead Republican negotiator of the First Step Act—the biggest criminal justice reform effort in a generation and a signature bipartisan accomplishment of the Trump Administration. Aaron also played key roles in the passage of the United States-Mexico-Canada Trade Agreement and the Infrastructure Investment and Jobs Act. Earlier in his career, he worked as an Associate Director of Presidential Speechwriting in the George W. Bush White House.  

Drawing on his years of experience in litigation, leading congressional investigations, and high-profile hearings on Capitol Hill, Aaron also counsels clients responding to government investigations.
