Katie Couric may not yet have made public where she’s going to land when she leaves “CBS Evening News” but her departing executive producer has already landed – at ABC News, where he will executive produce “This Week with Christiane Amanpour.” He will also oversee ABC News’s political coverage, ABC News president Ben Sherwood announced Thursday.

 “His mission: to lead This Week to #1 and to guide ABC News to dominance in the 2012 elections and beyond,” Sherwood said in a memo issued Thursday — which is also Kaplan’s last day at CBS News.

 Ian Cameron, the ABC News executive producer who helmed “This Week’s” re-launch when Christiane Amanpour became host, left the show at the end of 2010.

Though Kaplan started at CBS in the 70’s, his latest appointment is a homecoming of sorts for Kaplan. He spent about 20 years at ABC as executive producer of “Good Morning America,” “Nightline,” “PrimeTime Live,” and “World News Tonight with Peter Jennings.”

 Kaplan really gets around; 0ver the course of 40 years in news, he’s worked at four major networks and served as president of two cable news operations – MSNBC and CNN.

 Sherwood has known Kaplan since the summer of ’89, when Sherwood joined ABC News as an associate producer at “PrimeTime Live.”

“Screening pieces with Rick still evokes the most vivid, visceral memories. We all learned so much from Rick about storytelling, showmanship, and the fighting spirit,” Sherwood said, adding:

 “Welcome home, Rick. It's great to have you back.”
