Jack Dorsey, founder of Twitter, and Salman Khan, founder of the Khan Academy, will join President Bill Clinton at the 2013 Clinton Global Initiative University (CGI U) at Washington University in St. Louis April 5-7, 2013.

CGI U brings together students, youth organizations, topic experts and celebrities to discuss and develop innovative solutions to pressing global challenges.

During CGI U, the nearly 1,200 attendees will work on their Commitment to Action — a concrete plan that addresses a pressing challenge in one of CGI U’s five focus areas: education; environment and climate change; peace and human rights; poverty alleviation; or public health.

Dorsey, a St. Louis native, is an innovator widely known for creating the popular microblogging service Twitter. He also has launched Square, a mobile device that allows people to accept credit card payments through their mobile devices.

Khan is executive director and founder of the Khan Academy, a not-for-profit with the goal of “changing education for the better by providing a free world-class education for anyone anywhere.”

Khan Academy has an online library of over 3,900 videos covering everything from arithmetic to physics, finance and history and hundreds of skills to practice.

Additional CGI U presenters will be announced in advance of the April event.
