Defense Secretary Robert Gates has ordered an investigation into the leak of details from a draft study about gays in the military.
The report, not slated for release until after Dec. 1, concluded that allowing gays to serve openly would pose little harm to the military.
Details on the 370-page study were first reported Wednesday by The Washington Post and subsequently confirmed by other news organizations, including The Associated Press.
None of the information was classified. Opponents of repeal accused the Pentagon of leaking selective details to sway public perception.
Pentagon spokesman Geoff Morrell said in a statement Friday that "anonymous sources now risk undermining the integrity of the process."
