On May 13, 2009, President Obama turned to Gregory B. Jaczko, a PhD physicist with critical views of the nuclear power industry to chair the Nuclear Regulatory Commission (NRC), which is the foremost agency overseeing atomic energy. Senate confirmation was not required because Jaczko was already a member of the commission. At present, he is the only Democrat on the NRC, but that is expected to change soon. Former Chairman Dale Klein and Kristine Svinicki are Republicans, but two seats on the five-member commission are vacant. Although no more than three members of any one political party can be appointed to the commission, it is expected that President Obama will name two additional Democrats, creating a 3-2 majority.
