Why It Matters

The Senate Budget Committee hearing on Hal Duncan's Office of Management and Budget (OMB) nomination puts a spotlight on who will run the day-to-day operations of what Politico has called the "nerve center" of an administration. Duncan's confirmation hearing, scheduled for June 16, would install the number two official at the OMB at a moment when it is under fire from scientists, advocacy groups, and Democratic lawmakers over its budget and grantmaking agenda.

The Big Picture

OMB Director Russell Vought proposed an overhaul of the federal grantmaking system, reported by Axios on June 1, 2026, which the advocacy group Stand Up for Science described as "an unprecedented power grab" that would shift authority away from research agencies and Congress. Democrats have also criticized OMB for allegedly violating the spending law by proposing cuts that Congress had already rejected in the FY2026 budget. Vought defended the FY2027 budget request before Congress in April 2026.

The Hearing

President Trump formally nominated Hal Duncan on or around April 27, 2026, approximately seven weeks before the scheduled June 16 Senate Budget Committee hearing. Duncan, whose full name is Harold Peterson Duncan, is currently serving as Associate Director for Legislative Affairs at OMB and would replace James Bishop in the Deputy Director role. His nomination was referred jointly to the Senate Committees on the Budget and Homeland Security and Governmental Affairs.

Duncan's background is steeped in Capitol Hill. He previously served as legislative director for Representative Chip Roy (R-TX), held roles with Senator Pat Toomey (R-PA) and the National Republican Senatorial Committee, and holds a degree from the University of Virginia's Frank Batten School of Leadership and Public Policy.

The Bottom Line

The Hal Duncan OMB hearing will be chaired by Senator Lindsey Graham, with Senator Jeff Merkley serving as Ranking Member. The committee's membership spans some of the Senate's most prominent budget voices, including Senators Chuck Grassley, Ron Wyden, Patty Murray, and Bernie Sanders.

The Office of Management and Budget nomination comes as OMB's policy reach is being contested on multiple fronts, making the Duncan Deputy Director role more consequential than a typical management appointment.
