After the incident at the Cincinnati Zoo, sources from all over have called on Jack Hanna for his commentary.

On May 28, Cincinnati Zoo officials made the decision to shoot and kill Harambe, a 17-year-old silverback gorilla, after he grabbed a 4-year-old boy who climbed over a 3-foot-tall barrier and fell into a moat in the gorilla exhibit. Almost instantly, media requests began pouring in for Jack Hanna, director emeritus of the Columbus Zoo andAquarium.
