Washington: Senior U.S. lawmakers on Sunday condemned the suspected distribution of nude photographs of female Marines to military personnel and veterans via a social media network that promotes sexual violence, and called on the Marine Corps to fully investigate.

The Marine Corps Times, an independent newspaper focusing on issues involving the service, published an internal Marine Corps communications document with talking points about the issue, describing the social media network as a closed Facebook group with about 30,000 members. The network solicited nude photos of female service members, some of whom had their name, rank and duty station listed, the newspaper reported.
