Several Nobel Peace Prize winners are expected in Chicago for a three-day summit this week, the first of its kind in North America.
Laureates set to attend include former Soviet leader Mikhail Gorbachev, the Dalai Lama and former President Jimmy Carter. On Monday, they're scheduled to visit Chicago Public Schools and attend a dinner with former President Bill Clinton.
The World Summit of Nobel Peace Laureates has taken place for a dozen years, but it's the first one held in North America.
The event runs through Wednesday at the University of Illinois at Chicago. The theme is "Speak Up, Speak Out for Freedom and Rights."
Illinois Gov. Pat Quinn and Chicago Mayor Rahm Emanuel are event co-chairs.
The gathering happens just weeks before foreign dignitaries arrive for the NATO summit.
