Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Department of Defense relating to "Cybersecurity Maturity Model Certification (CMMC) Program".

H.J.Res. 221 is a joint resolution disapproving a Department of Defense rule published on October 15, 2024, that would have established the Cybersecurity Maturity Model Certification (CMMC) Program for defense contractors. The rule required contractors working with the Department of Defense to meet specific cybersecurity standards under the CMMC framework. If enacted, this resolution would block the rule from taking effect, preventing the CMMC program from being implemented as proposed. The bill targets a procedural disapproval mechanism under federal law, not new policy.
