Brandon Williams appeared before the U.S. Senate’s Committee on Armed Services this week to answer questions on how he would lead the Department of Energy’s National Nuclear Security Administration, if confirmed for the job.

President Donald Trump announced Williams as his pick for the NNSA role in January. Energy Secretary Chris Wright said he was personally involved in the selection of Williams for the role, telling the Exchange Monitor in January, “He’s a smart, passionate guy [who] wants to defend our country.”
