At a gay rights dinner on Saturday night, President Obama repeated as promise he made during last year's campaign, that of ending the exclusion of gays in the military. Obama could revoke Bill Clinton's "Don't Ask, Don't Tell," policy, but it will take an act of Congress to repeal the ban. Hard-line activists say Obama is moving too slowly, but now from the Pentagon's highest levels comes a call for the repeal of the ban. An article for the Joint Chiefs of Staff says there's "no scientific evidence" that gays and lesbians damage morale," but that, in the meantime, they're required to live a lie. Is Congress likely to listen?
