APA President Carol Bernstein, M.D., reiterated APA's strong opposition to the U.S. military's "Don't Ask, Don't Tell" policy in a letter to Senate Majority Leader Harry Reid (D-Nev.) in July. The policy, in effect since 1993, allows all branches of the military to discharge service members who are open about being gay or lesbian. While it prohibits unit leaders from initiating investigations of someone's sexual orientation, the law does permit them to pursue an investigation if "credible" evidence that someone is gay or lesbian is brought to their attention.
