Obama's presidency just got a little more historic. On Saturday, he plans to appoint his administration’s first openly gay ambassador, lawyer David Huebner, who currently serves as the general counsel for the Gay and Lesbian Alliance Against Discrimination. If confirmed, Huebner would serve as U.S. ambassador to New Zealand and Samoa. The nomination comes as Obama faces criticism from gay leaders who believe that he is not following up on campaign promises, including repealing the military's "Don't Ask, Don't Tell" policy. The president has timed the official nomination to a speech he's giving on Saturday night to the Human Rights Campaign, a proponent of equal rights for gays.
