It's the issue that got Bill Clinton's presidency off on something of the wrong foot - gays in the military.And now, more than 100 retired generals and admirals are urging President-elect Barack Obama to tackle it early as well.Over the objections of many in the military, Clinton lifted the ban on homosexuals and pushed through a "don't ask, don't tell" policy - a compromise of sorts that allows gays to serve as long as they are not open about their sexuality.Critics, however, say the policy has cost the military many highly qualified people at a time when it is fighting two wars and having some difficulty finding recruits.During the campaign, Obama said that he will work with Pentagon leaders to repeal the "don't ask, don't tell" policy, but his adviser, retired Air Force General Merrill McPeak, said that the policy should be retained.
