Aaron Szabo

Aaron Szabo is an American lawyer, lobbyist, and government official who has served as assistant administrator of the United States Environmental Protection Agency for air and radiation since August 25, 2025, a position to which he was appointed by President Donald Trump. In that post he directs the EPA Office of Air and Radiation. In the Trump administration, Szabo has been part of efforts to deregulate environmental and health regulations, saying that the deregulatory measures would "reduce red tape and bring common sense back to rulemaking."

Szabo held environmental posts in the first Trump administration as senior counsel at the White House Council on Environmental Quality, and in policy positions at the Office of Management and Budget and Nuclear Regulatory Commission. American Fuel and Petrochemical Manufacturers opposes stricter standards for particulate pollution. Shortly after joining the EPA, Szabo was involving in weakening regulation of particulate pollution. Szabo was thanked by name in the EPA chapter of Project 2025. Democrats criticized Szabo's appointment to the EPA, pointing to his lobbying past for oil and chemical industries. Senator Sheldon Whitehouse said, "Now he can do Big Oil’s dirty work from inside the EPA."
