Final answer:
True, President Obama repealed the 'Don't Ask, Don't Tell' policy in 2011, allowing gay and lesbian individuals to serve openly in the military, marking a significant victory for gay rights.
Step-by-step explanation:
The statement is true. In 2011, President Obama signed legislation that officially repealed the "Don't Ask, Don't Tell" (DADT) policy, which was a military directive that had been in place since December 1993. The DADT policy allowed gay and lesbian individuals to serve in the military only if their sexual orientation was not disclosed. The repeal was a significant milestone in the history of gay rights in the United States Armed Forces and followed many years of legal challenges and political activism aimed at ending the ban on openly gay military service members.
