In a series of e-mails, members of the ropeline platoon reported on the movement of journalists, especially Dan Merica, a CNN producer covering the Clinton campaign.

After an advance staffer wrote to report that an aggressive French journalist was “at stage right,” the Merica tracking kicked in.

“Watch out for Dan Merica center right,” a press aide warned. Eight minutes later, an advance team member wrote, “Dan Merica stage left.” A minute later Hamilton advised colleagues, “French journos and dan merica heading to stage right.” Moments later, a new Merica update came from an advance team member: “Dan America is on backstage bleachers.” Less than a minute later, the staffer gave an update: “I’m with dan America on back stage bleachers.”

It appears Merica was being secretly tracked by campaign workers concerned that the CNN employee might detonate a question if he got too close to any of the Clintons.
