Since it was published in 2006, Greg Mortenson's "Three Cups of Tea" has sold millions of copies. This inspirational tale about one man who set out to build schools and promote literacy in Pakistan and Afghanistan has become a book club favorite and required reading in many high school English classes.
But now, Mortenson is under fire following a Sunday report from CBS's "60 Minutes" that questions how he spent millions of dollars and whether some of the most dramatic stories in his book are true.
Mortenson has issued a statement denying the allegations. His publisher, Viking, says it will review the materials in the book with the author. Read the "60 Minutes" transcript here.
