Thursday’s announcement about Christianne Klein‘s move to ABC News caused a bit of e-mail traffic at ABC, a tipster says. So the executive producer of overnight and morning news sent out this clarification about Klein’s gig: “Just to clarify — She is coming aboard as the WEEKEND overnight standby anchor and GMA reporter. She will also anchor ABC News Now. While she may well fill in for Ron or Tai from time to time someday down the road, that is not her current role.”
