Mr. Bush’s financial ties are the focus of a planned 38-page e-book by Peter Schweizer, the researcher who recently chronicled the financial entanglements of the Clinton family in the book “Clinton Cash.” (The New York Times was one of at least three news organizations to receive a copy of the report before its publication. There were no agreements or conditions concerning how the contents would be used; The Times vetted the information and built on it with its own reporting.)
