North Dakota's US senators aren't happy about what they're hearing regarding a possible environmental study of silos that hold the nation's nuclear-tipped missiles.
Heidi Heitkamp and John Hoeven issued a statement calling on the Department of Defense to follow federal law and put a stop to any such environmental study.
Part of the latest Defense Department appropriations bill blocked the administration from eliminating any operational missile silos.
That would keep the department from reducing the number from the current 450 Minuteman Three silos in North Dakota, Wyoming, and Montana.
But the senators say they are hearing the department is trying to circumvent that language in the law by implementing an environmental study that might lead to a call for eliminating some silos.
Their letter to the Defense Department demands to know the legal justification for contradicting the law.
And they ask for assurances that the seemingly illegal move will not be carried out.
The letter is signed by Heitkamp, Hoeven, and Montana Senators Jon Tester and John Walsh.
