On July 31, 2015, a Justice Department prosecutor calls Clinton’s personal lawyer David Kendall seeking a thumb drive that contained a copy of the 30,000 emails that Clinton had already turned over to the State Department, according to a person briefed about the conversation.

On August 6, 2015, Kendall gives the FBI his thumb drive, as well as two copies. (The Washington Post, 8/14/2015)
