Bush had opened up the 332,999 emails to public scrutiny, seeking to portray himself as a tech-savvy executive, in touch with constituents and an active administrator. But tucked away in some of the messages were the personal details of thousands of people. “This was obviously very innocent,” said Todd Feinman, the chief executive of data security firm Identity Finder. “But now we have more than 12,000 individuals who are exposed to the risks of identity fraud.” By Thursday Bush’s team had removed the private information from all but a few hundred of the emails that were posted to a website on Tuesday. “We have redacted every account that we have found,” Bush spokeswoman Kristy Campbell said.
