Nelson says a decision by the Department of Homeland Security will leave the state $500,000 short when it comes to security.
According to the Associated Press, the Nebraska democrat says the decision disregards minimum allocation of grants mandated by law.
He says Nebraska is entitled to $6.5 million in fiscal 2009 under the formula, but the targeted allocation would deny the state $464,000.
Nelson says Nebraska is one of 18 states affected, and he has written to the department challenging the "complete disregard" of the law.
Previous grants have been used to enhance communication capability and buy equipment to deal with chemical, biological and radioactive material.
