If you're a regular watcher of The Oprah Winfrey Show, you -- like me -- will recall the powerful reports created by Lisa Ling. The journalist attacks interesting stories and is intrepid and dogged in her reporting. She's found a new place to do her work. Lisa Ling is joining Nightline.

"I have wanted to work with Lisa for a long time," said James Goldston, ABC News and Nightlines' executive producer. "She is a terrific journalist with a very distinctive style that fits really well with the Nightline sensibility."

Lisa will continue with her Oprah appearances. She will also host National Geographic Ultimate Explorer.

Lisa's initial report for Nightline debuts tonight. It's a look at the growth of luxury retirement communities. If you're thinking Del Boca Vista, the Seinfeld show condominium where Jerry's parents lived, so did I.
