A US federal law enforcement agency confirmed it’s opened an investigation into Robert F. Kennedy Jr. after he allegedly cut off the head of a dead whale and took it home two decades ago, reports AP. The former independent presidential candidate disclosed the investigation while campaigning outside Phoenix for Donald Trump. 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. Kathleen Kennedy said when she was 6 years old, her dad got word that a dead whale had washed ashore. He got a chainsaw, cut off the whale’s head and strapped it to the roof of their minivan for a five-hour drive home. “Every time we accelerated on the highway, whale juice would pour into the windows of the car, and it was the rankest thing on the planet,” Kathleen Kennedy recalls. “We all had plastic bags over our heads with mouth holes cut out, and people on the highway were giving us the finger, but that was just normal day-to-day stuff for us. Kennedy told a crowd of Trump supporters in Glendale, Arizona, that he received a letter “saying they were investigating me for collecting a whale specimen 20 years ago.” Without confirming or denying he took the severed whale head, Kennedy said the deadline to bring charges passed long ago. He implied without evidence that the investigation was tied to his endorsement of Trump. Kennedy dropped out of the presidential race in late August. In the US, even a dead whale and its remains belong to the government, and trying to take them is illegal.
