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

The National Oceanic and Atmospheric Administration confirmed on Monday it is investigating RFK Jr. to find out if he decapitated a dead whale twenty years ago.

"I received a letter from the National Marine Fisheries Institute saying that they were investigating me for collecting a whale specimen 20 years ago," he stated at the event.
