After weeks of silence and uncertainty , the agency responsible for for ensuring the safe of our nuclear arsenal finally has an answer to the doubt of who on the nose is in bursting charge under President Trump . Last night , just hours before Trump was to be avow in , his transition team eventually asked Under Secretary for Nuclear Security Frank Klotz to stay on as gaffer of the National Nuclear Security Administration until his eventual successor could be bring up and confirmed by the Senate .

As is wonted for political appointment in outgoing government activity , Klotz had put in his surrender effective today at noon . But it ’s also been customary for unexampled president to invite drawing card in central positions — like , say , the ones ensuring the refuge of our nukes — to stick around until the new president is able to install his own people . The Trump transition , as Gizmodo previously report , had provide Klotz nothing but secretiveness on that enquiry for week , result him to prepare for departure and spreading anxiety in the nuclear community that a fundamental agency would be left leaderless due to Trump ’s inattention .

The issue come to a head on Tuesday , when Sen. Martin Heinrich ( vitamin D - NM)sent Trump a letterwarning him that “ our nation will miss richly - grade officials in direction of critical responsibilities such as overseeing our nation ’s atomic backlog . ”

On Wednesday , harmonize to an functionary within the Department of Energy , which house the NNSA , Trump ’s energy secretary campaigner Rick Perry stopped by the office to meet with Klotz . “ Perry was very pointed , ” the official told us . “ He said something along the lines of ‘ I ca n’t tell you to ride out because I ’m not sustain , but that ’s my aim . ’ ” Then , at some degree late yesterday — less than 24 time of day before he was to be assert in — Trump seems to have in conclusion need Klotz to continue on in his office as NNSA administrator in the interim . An email from Klotz to his co-worker , obtained by Gizmodo , confirms that “ to aid ensure continuity in our critical atomic surety work , I ’ve been asked to continue as the NNSA Administrator for a full stop of time . ”

accord to the Department of Energy functionary , Klotz had been preparing for retirement , going so far as to pack up his property . Even though the invitation was extend at the last moment , the source told Gizmodo , Klotz agreed to stay on out of a sense of duty . “ At the end of the mean solar day , he ’s a mortal who spend 40 year serving his land , ” the official said . “ I do n’t think that he would ever want to just pull up stakes us empty - handed . ”

As for the rest of the NNSA , Klotz ’s note to colleagues foretell the departure of his surrogate , Madelyn Creedon , and seven other senior staffer . The Department of Energy official enjoin the NNSA has received no guidance on how many staff will be fall in to interchange them , or when .

When asked for confirmation that Klotz was still in command , an NNSA interpreter told us , “ All I can do right now is refer you to what Gov. Perry said in his check audience yesterday ” ( Perry , when asked about the NNSA leadership , suppose only that “ we ’re quite confident that our procedure is ferment . ” )

The Trump team did not return our requests for scuttlebutt .
