Nieh confirmed for the NRC
Nieh
Earlier today, the U.S. Senate officially confirmed Ho Nieh in a 66–32 vote to serve as a commissioner on the U.S. Nuclear Regulatory Commission through the remainder of a term that will expire June 30, 2029. All present Republicans, alongside 15 Democrats and one Independent, cast their votes in favor of Nieh, who was nominated by President Trump in July and fills the seat left vacant following the dismissal of former commissioner Christopher Hanson.
NRC details: The commission leading the NRC now comprises four members. Nieh joins Chair David Wright and commissioners Bradley Crowell and Matthew Marzano. One spot remains unfilled after the resignation of Annie Caputo in July. President Trump nominated Douglas Weaver earlier this month to fill Caputo’s seat.
