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. Christopher Hanson, a former chairman of the U.S. Nuclear Regulatory Commission, said in a statement Monday that Trump terminated his position as NRC commissioner without cause, “contrary to existing law and longstanding precedent regarding removal of independent agency appointees.” The firing of Hanson comes as Trump seeks to take authority away from the independent safety agency, which has regulated the U.S. nuclear industry for five decades.
