"On December 22, 2010, President Obama signed P.L. [Public Law] 111-321 into law. It called for the repeal of the existing law (Title 10, United States Code, §654) barring open homosexuality in the military by prescribing a series of steps that must take place before repeal occurs. One step was fulfilled on July 22, 2011, when the President signed the certification of the process ending the Don't Ask, Don't Tell policy, which was repealed on September 20, 2011. However, in repealing the law and the so-called 'Don't Ask, Don't Tell' policy, a number of issues have been raised, but were not addressed by P.L. 111-321. This report considers issues that Congress may wish to consider regarding matters arising as a result of the repeal of §654."
