Jonathan Greenberger has been named executive broadcast producer of ABC’s “This Week.”

It is a return to ABC News for Greenberger, 30, who started out as an assistant to “This Week” host George Stephanopoulos. He most recently served as the program’s senior producer, helping to re-launch the show when Stephanopoulos was named its anchor in 2011. Greenberger left the network to finish up his law degree, recently receiving his JD from Stanford Law School.

In a memo to staffers this morning, ABC News president Ben Sherwood noted Greenberger’s “passion for politics” and said he would help lead the Sunday public affairs show to “even greater success.”

Greenberger replaces Sandy Cannold, who was promoted to executive producer and senior business editor of ABC News earlier this year.
