The
House of Representatives bill was introduced on July 2, 2021, by Rep.
Adam Smith of Washington state, the chair of the
House Armed Services Committee. Markup began on July 28. 780 amendments were made during markup, which ended on August 31. A corresponding
Senate bill, , was introduced on September 22. The House approved their version of the bill in a 316 to 113 vote on September 23. It included a provision that women, like men, should be required to register for
Selective Service. However, this was later removed from the final bill. The Senate approved to move forward and consider the House's version of the NDAA instead of theirs on November 17, by a 84 to 15 vote. Conflict in the Senate led the version of the bill introduced in the Senate to be placed on hold, due to objections by Senator
Marco Rubio over the attached amendment package. A compromise bill was created through a previously introduced Senate bill, S. 1605 on December 7, and the House passed it on the same day with bipartisan support, which removed some of the provisions in the Senate version of the NDAA bill. On December 15, the compromise bill was passed by the Senate in a 88–11 vote. President
Joe Biden signed the NDAA 2022 into law on December 27, 2021. In his
signing statement, Biden expressed reservations about restrictions on transferring Guantánamo Bay detainees, potential infringements on the President's authority to protect sensitive national security information, and the constitutionality of Senate confirmation for certain executive branch working group members. ==Provisions==
