Tomlin pushes for zoo to retire aging elephant

Comedian and animal-rights advocate Lily Tomlin says Jenny the elephant has worked 22 years for the Dallas Zoo and it's time for the aging pachyderm to retire.

Tomlin, who has seen video footage of Jenny appearing in distress, visited the Dallas Zoo for the first time Friday to view the elephant in her habitat.

"It's heartbreaking," Tomlin said. "If you know anything about elephants ... you would just ache for her. We'd like her to go the sanctuary now."

The actress has been in Dallas most of the week, working with Concerned Citizens for Jenny. The group wants the zoo's lone 32-year-old elephant sent to the Elephant Sanctuary in Hohenwald, Tenn., which has a large area where Jenny can roam on hundreds of acres and socialize with other elephants.
