WASHINGTON ― House appropriators on Tuesday approved a spending bill that would block plans from defense hawks to give the Pentagon a stronger hand in crafting nuclear weapons budgets.

The House Appropriations Energy & Water Development Subcommittee passed their bill, which contained the provision, by a voice vote. The $49.6 billion spending bill contained $13.7 billion for nuclear weapons accounts ― a $1.2 billion increase over fiscal 2020 that’s still $1.9 billion less than the president’s request.

Lead Republicans voiced opposition to the bill, arguing that Democrats had not consulted with Republicans on pandemic emergency funds in the bill and that Democrats included policy riders the White House will seek to cut. The top Republican on the subpanel, Rep. Mike Simpson of Idaho, said the bill “still shortchanges funding for the nuclear weapons program.”

“While I acknowledge the increase above last year, we must also acknowledge that the threats we face today are not the same threats we faced in the years immediately following the end of the Cold War,” he said. “We must adequately fund the activities necessary to maintain a safe, reliable and effective stockpile.”

The bill would bar funding for the Pentagon-led Nuclear Weapons Council, and would prevent it from assisting with the budget of the National Nuclear Security Administration, a semiautonomous agency under the Energy Department.

The Senate Armed Services Committee’s version of the annual defense policy bill would allow the council to edit the budget request after the Energy Department crafts it and before the request is submitted to the White House budget office. The move was seen as giving the Pentagon extra sway to boost warhead programs and nuclear weapons laboratories.

Its introduction came after Energy Secretary Dan Brouillette clashed with SASC Chairman Jim Inhofe, R-Okla., who backed a budget request for the larger number than Brouillette sought.

The Energy-Water spending bill contains language ordering no funds “may be used in furtherance of working through the Nuclear Weapons Council to guide, advise, assist, develop, or execute a budget for the National Nuclear Security Administration.”

Separately, the proposed bill would ban the Trump administration’s reported plan to resume nuclear weapons testing. The bill would prohibit funding “to conduct, or prepare to conduct, any explosive nuclear weapons test that produces any yield.”

“Critically, the bill would prevent the Trump administration from using any funds to carry out its dangerous and short-sighted plan to resume nuclear testing,” House Appropriations Committee Chairwoman Nita Lowey, D-N.Y., said in a statement.

The Trump administration was reportedly discussing whether a “rapid test” could aid it in negotiations with Russia and China, as the White House seeks a trilateral nuclear weapons pact.

The defense appropriations bill introduced Tuesday would also bar funding for explosive nuclear weapons tests.
