On Tuesday, several the nation's top military officials, including Admiral Mike Mullen, Chairman of the Joint Chiefs of Staff, and Defense Secretary Robert Gates, spoke out in favor of ending Don't Ask, Don't Tell, the Clinton-era policy that can get a lesbian or gay service person fired if their sexuality becomes known. Mullen tweeted later: ?Stand by what I said: Allowing homosexuals to serve openly is the right thing to do. Comes down to integrity.? Hoorah!
