The highest-ranking official known to lose their job in Jeb Bush's flagging campaign is Christine Ciccone, the campaign's chief operating officer. News of Ms. Ciccone's departure comes a week after the Bush campaign announced a re-organization that it said would reduce payroll by 40%. Ms. Ciccone served as Mr. Bush's chief operating officer, effectively an office administrator responsible for logistics. "We are grateful to have had Christine on the team, we respect her immensely," Bush spokesman Tim Miller said.
