This year will mark 20 years since Steve Irwin‘s unexpected death, and Robert Irwin is opening up about how he continues to deal with the loss. Robert appeared on the Tuesday, March 10, episode of Anderson Cooper‘s All There Is podcast, on which the CNN host and his guests open up about their experiences with grief. While Robert has used his platform to continue his father’s wildlife conservation legacy over the years, one of Cooper’s questions made him particularly emotional. “Do you talk to your dad?” Cooper asked. Noticing Robert begin to choke up, he stated, “If it’s too personal, it’s fine.” Robert assured him he was Ok before responding.
