 A man who's considered a superstar in lending money to the poor is on trial starting today. Muhammad Yunus is known for advancing the idea of micro-lending, helping people improve their living conditions or get a business going by granting very, very small loans. He and his colleagues with the Grameen Bank won the Nobel Peace Prize for their efforts years ago. Now in his homeland of Bangladesh, he and 13 others face charges of embezzlement and corruption.
