Iowa Code § 17A.21
If it is determined by the attorney general that any provision of this chapter would cause denial of funds or services from the United States government which would otherwise be available to an agency of this state, or would otherwise be inconsistent with requirements of federal law, such provision shall be suspended as to such agency, but only to the extent necessary to prevent denial of such funds or services or to eliminate the inconsistency with federal requirements. If the attorney general makes such a suspension determination, the attorney general shall report it to the general assembly at its next session. This report shall include any recommendations in regard to corrective legislation needed to conform this chapter with the federal law.
