In a surprise move Monday, President Obama announced that the G8 summit will be held at Camp David, not Chicago. Eight Forty-Eight gets analysis from WBEZ reporter Alex Keefe. Chicago Alderman Bob Fioretti, whose ward includes where the summit was to be held, weighs in on the change. And, the play Time Stands Still, now on stage at Steppenwolf Theatre, follows a female photojournalist and her personal struggles after returning home injured from an assignment. Playwright Donald Margulies and Los Angeles Times photographer Carolyn Cole talk about the inspiration behind the work, and what it’s like to photograph tragedy. Normally, by the time the Illinois Republican primary rolls around, the presidential nominee has already been locked in. Not this time, says David Yepsen, director of Southern Illinois University’s Paul Simon Public Policy Institute. He explains the unexpected relevance of Illinois’ March 20 primary.
