Wow. This is a doozy. Check out this 60 Minutes feature about Greg Mortenson, philanthropist and author of the bestseller Three Cups of Tea and its follow-up, Stones Into Schools.
Turns out that there is pretty compelling evidence showing that information from his supposed autobiographical books is false. 60 Minutes was able to track down some of the people involved in the stories, who backed up these claims. The charity watchdog group, American Institute of Philanthropy, is also very wary about how Greg is using donations made by the public to his charity, Central Asia Institute.
