RFK Jr, also known as Robert F Kennedy Junior, admitted to cutting the penis out of a road killed raccoon in a diary entry from 2001 that was uncovered by journalist Isabel Vincent and included in her new book. He claimed that he wanted to study the raccoon's genitals later. RFK Jr also mentioned having a freezer full of roadkill and a skull collection that he hopes to expand with the heads of dead seagulls.

Since the start of Donald Trump's second presidential campaign in 2024, stories about RFK Jr's strange behavior towards animals have been circulating widely. These include dumping a dead bird in Central Park as a prank, beheading a dead whale with a chainsaw, and feeding baby chickens and mice to his hawks. RFK Jr's cousin Caroline Kennedy even described him as a predator. In a similar vein, former DHS Secretary Kristi Noem wrote about shooting her own dog because it was untrainable, sparking controversy.
