Back in early 2014, a media leak revealed Robby Mook was being considered to run a possible presidential campaign by Hillary Clinton.
In fact, the 36-year-old was already on the job -- almost three years before the vote.
"You are right abt a long term press strategy. Need a different voice responding to this stuff," Mook wrote to Cheryl Mills, Clinton's longtime aide, in February 2014.
Mook's message was among the thousands of gmail messages hacked from the account of John Podesta, Clinton's campaign chairman, and released in recent days by WikiLeaks.
