Charlie Baker, the chief operating officer of the Clinton campaign, said that in 2015 the campaign agreed to raise money for the parts of the DNC that were going to be most crucial to the general election, including data, research, communications and the like. The agreement also gave the Clinton campaign some say over personnel. If there was a vacancy for a position in one of these departments, the DNC had to consult the campaign on the three finalists but could make the final decision itself.
