Reaction to Mike Daisey's Foxconn claims

Performance artist Mike Daisey in his one-man show, "The Agony and the Ecstasy of Steve Jobs."

(CBS News) Several weeks ago "Sunday Morning" brought you a story about working conditions at a factory in China where a number of electronics products - iPhones and iPads among them - are assembled.

On Friday the NPR radio program "This American Life" announced it was retracting a report based on a portion of a theatrical performance by monologist Mike Daisey highly critical of labor conditions at the plant.

It found that Daisey had exaggerated some of his findings.

Our story, broadcast January 29, featured Mike Daisey, too. But we heard from other critics as well.

In an excerpt we featured from Daisey's monologue, he describes meeting workers as young as 12 at the plant - a claim which has been called into question.

We've been unable to confirm that account - but neither Apple nor Foxconn would grant us an interview to deny it.

And we've independently confirmed all other aspects of our "Sunday Morning" story.
