Kennedy’s daughter recalled the whale incident in a 2012 interview with Town and Country magazine, which recently resurfaced and was shared on social media.

The 70-year-old former presidential candidate did not go into detail about the decapitation of the whale, but his daughter previously described how he had used a chainsaw to cut the head off a dead whale 30 years ago.

Katherine Silverstein, a spokesperson for NOAA, told the Times that the federal agency typically does not comment on open investigations.

Kennedy Jr. is under federal investigation for an incident involving a dead whale that dates back two decades. The National Marine Fisheries Service confirmed the probe, which follows allegations that Kennedy cut off the head of a deceased whale and transported it home.
