US Secretary of State Hillary Clinton and actor Ben Affleck kick off “Call to Action for Child Survival,” organized by the US, Ethiopian and Indian governments at Georgetown University in Washington, DC. More than 700 government, private and civil society leaders are attending the event. Among them is Sen. Pia Cayetano, who tweeted updates and photos. According to USAID’s Rajiv Shah, this year alone, more than 7 and a half million children will die before their 5th birthday. Affleck, who started the Eastern Congo Initiative calls this “abhorrent” and “unacceptable.” Affleck opened his Twitter account Thursday. @BenAffleck‘s first tweet: “Timing feels right to bring awareness to what’s happening in the #Congo today & to share my stories from this part of the world.” Clinton said that saving the lives of children “cannot just be the job for governments,” stressing the importance of “shared responsibility” between other partners, including the private sector, non-profit groups and faith-based organizations.
