Marie Harf, a top adviser to Secretary of State John Kerry, said Wednesday that she is not responsible for pushing to selectively edit a State Department briefing video in 2013 to delete a discussion about the Iran nuclear agreement, and has no knowledge about who made that decision.

Harf is Kerry’s senior adviser for strategic communications, and previously served as State’s acting spokeswoman and deputy spokesman when the video edit was made. Harf joins her former colleague, White House Communications Director Jen Psaki, in denying involvement in the purposeful decision to edit the video, an act that the State Department confirmed on Wednesday.
