Co-producer is a crew position in television. It is a more junior position for a producer. Co-producers usually work with more senior producers on a single aspect of production.
Lauren Lohman, Eli Bush, and Dauri Chase were Co-producers for the series pilot "We Just Decided To". They all returned when the first season was ordered. Lohman has previously worked as Sorkin's assistant during The West Wing and was an Associate Producer for Studio 60 on the Sunset Strip. Christine Larson-Nitzsche also joined them as a Co-producer and took over Unit Production Manager responsibilities from Producer Leanne Moore from the second episode "News Night 2.0" onwards.
