Jenny Lee on growing up with a chimp

When Jenny Lee was 13, an unusual guest joined her family: a chimpanzee.

Nim, the 3-year old chimp, became “like a brother” to her, Lee says, while he lived and played with her family in a controversial experiment to teach the chimp sign language.

Lee joins “Starting Point” Thursday to discuss Nim’s stay with her family, which is featured in an HBO documentary “Project Nim,” debuting Thursday on HBO at 9 p.m.
