President Donald Trump has fired a Democratic commissioner for the federal agency that oversees nuclear safety as he continues to assert more control over independent regulatory agencies.

Hanson was appointed to the NRC by Trump in 2020 and named chair by then-President Joe Biden in 2021. His renomination by Biden was approved by the Senate in 2024 with a large bipartisan majority. Hanson, however, was notified of his dismissal in a terse, two-sentence email from the White House that concluded, “Thank you for your service.”
