Washington( CNN) A handful of the emails and documents hacked from the private email account of Hillary Clinton's campaign chairman, John Podesta, detail the at-times uncomfortable overlap between the family charity and the public and private sector careers of the Clintons, dating back long before Clinton's formal campaign for chairman began.

The anxiety — centered around the nexus of Clinton Foundation fundraising, paid speeches and requests for access to former President Bill Clinton dubbed “Bill Clinton Inc.” by a top aide — dates back to late 2011, when Chelsea Clinton began to take on a greater role in the family foundation and spearheaded an attempt to clean house.
