A State Department spokesman defended Monday a set of call logs that showed Hillary Clinton’s former chief of staff, Cheryl Mills, received more than 150 messages from a Clinton Foundation executive while working at the State Department.

“For senior aides in the department at that time to have connections with the Clinton Foundation … only speaks to the fact that these were important people who had reason to convey information to the secretary,” State Department spokesman Mark Toner said of the frequent contact Clinton’s staff had with Clinton Foundation donors and employees.
