HELENA - Montana's attorney general launched an inquiry Tuesday into the charity run by "Three Cups of Tea" co-author Greg Mortenson after reports questioned whether Mortenson benefited from money donated to build schools in Pakistan and Afghanistan.

Attorney General Steve Bullock's statement Tuesday to The Associated Press follows investigations by "60 Minutes" and author Jon Krakauer into inaccuracies in the book and how money donated to the Bozeman, Mont.-based Central Asia Institute was spent.

Bullock oversees non-profit corporations operating in the state. He has been in contact with attorneys for the agency, and they have pledged their full cooperation, he said.

"While looking into this issue, my office will not jump to any conclusions - but we have a responsibility to make sure charitable assets are used for their intended purposes," he said in the statement.

Bullock spokesman Kevin O'Brien said the inquiry has not reached the level of a full-scale investigation and it was not immediately clear exactly what Bullock was seeking.

"Those are the things that are going to have to come out in the coming days," O'Brien said.
