A former U.S. attorney said the FBI’s reported investigation of “public corruption” at the Clinton Foundation has actually been going on for months, although it made headlines for the first time Monday.

Joseph DiGenova, who was appointed by President Ronald Reagan, said the FBI’s foundation probe “has reached such a proportion of inquiry that it’s starting to sneak out,” but that it was sparked months ago by information pulled from Hillary Clinton’s private server and from the tax filings of corporations that have donated to the charity.
