President Donald Trump has tapped Ho K. Nieh to chair the five-member Nuclear Regulatory Commission (NRC), the third leadership change in less than a year at the nation’s nuclear safety agency.
Nieh was among two commissioners appointed in December 2025 to fill seats vacated by Christopher Hanson, who was fired in June after being removed as chair on the president’s first day in office, and Annie Caputo, who resigned in July.
