The hip-shaking Colombian pop star Shakira was in Washington, D.C., on Tuesday for an unlikely reason. She wasn’t there to put on a concert, but rather to lobby Congress to endorse bipartisan legislation that would help pay for education for the 72 million children worldwide who are too poor to go to school. The bill, known as the Education for All Act, would increase U.S. funding for universal education incrementally from the current level of $465 million to $3 billion by 2012.
