Decrying the Trump administration’s firing of hundreds of workers at the agency in charge of nuclear weapons safety, a bicameral group of Democratic U.S. lawmakers on Thursday asked Energy Secretary Chris Wright to provide assurances that members of Elon Musk’s Department of Government Efficiency cannot access classified systems or information.

“DOGE fired up to 350 staff members at the National Nuclear Security Administration. The NNSA is entrusted with safeguarding our nation’s nuclear weapons, materials, and secrets,” Rep. John Garamendi (Calif.) and Sens. Ed Markey (Mass.), Peter Welch (Vt.), Elizabeth Warren (Mass.), Jacky Rosen (Nev.), Cory Booker (N.J.), and Jeff Merkley (Ore.) wrote in a
letter to Wright.

“Recklessly firing personnel without a strategic plan… is extraordinarily irresponsible and dangerous to U.S. national security.”

“These terminations jeopardize the security of the U.S. nuclear stockpile, weaken our ability to detect and prevent threats to those weapons, and undermine our nonproliferation commitments,” the letter asserts.

“Realizing the gravity of the mistake it had made, the Trump administration scrambled to rehire the fired employees,” the Democrats noted. “Serious damage has been done. We urge you to immediately reassess these decisions, restore necessary expertise to the NNSA, and ensure that NNSA staffing decisions prioritize safety and security.”

The letter continues:

The NNSA plays an essential role in maintaining the safety, security, and effectiveness of the U.S. nuclear arsenal and preventing the proliferation of weapons of mass destruction. According to press reports, these firings occurred because “the officials did not seem to know this agency oversees America’s nuclear weapons.” The reckless decision to eliminate 350 positions, without a clear national security justification, raises serious concerns about the Department of Energy’s (DOE) commitment to this core mission. DOE has struggled to rehire some of these employees “because they didn’t have their new contact information.” This series of events calls into further question DOGE’s competence to carry out its self-assigned task.

While the lawmakers “fully support efforts to reduce our reliance on nuclear weapons, responsibly reduce the nuclear stockpile, and curb unnecessary spending on nuclear defense programs that do not enhance our security,” they argued in the letter that “recklessly firing personnel without a strategic plan, particularly those with expertise in nonproliferation, security, and arms control oversight, is extraordinarily irresponsible and dangerous to U.S. national security.”

The legislators are asking Wright to explain the process behind the NNSA officials’ firings, the DOE’s strategy for ensuring effective staffing and oversight at the agency, which workers have been rehired, and what steps are being taken to prevent unauthorized access to classified systems by DOGE members.

“There is a right way to reduce the size and scope of our nuclear arsenal—one that enhances global security, properly safeguards our weapons, and reduces nuclear risks,” the letter concludes. “These terminations do none of that.”

Thursday’s letter follows one
sent to Wright last week by Markey and Rep. Don Beyer (D-Va.) seeking clarification about whether any DOGE members have access to classified information about the nation’s nuclear arsenal.

It also comes as global experts warn about the risk of nuclear war. The Bulletin of the Atomic Scientists last month moved the Doomsday Clock “from 90 seconds to 89 seconds to midnight—the closest it has ever been to catastrophe.”
