Caroline Kennedy calls cousin RFK Jr. a 'predator' who would 'show off' killing of baby birds on eve of confirmation hearing

Caroline Kennedy has released an extraordinary video of comments to senators where she calls her cousin RFK Jr. a 'predator' who set family members on a path to drug addiction and mistreated small animals.

The daughter of president John F. Kennedy said she held back on criticism of her cousin during his failed presidential campaign due to her role as U.S. ambassador to Australia. 

But she unloaded on her famous cousin in her statement on the eve of his Senate confirmation hearing, as he faces an uncertain future in the Senate as Donald Trump's pick to lead the Health and Human Services Department. 

'I have known Bobby my whole life; we grew up together,' she said in a video posted by her son Jack Schlossberg.

 'It's no surprise that he keeps birds of prey as pets because he himself is a predator,' she said.

'He's always been charismatic. Able to attract others with the strength of his personality, his willingness to take risks and break the rules. I watched his younger brothers and cousins follow him down the path of drug addiction.  

'His basement, his garage, his dorm room were the centers of the action where drugs were available, and he enjoyed showing off how he put baby chickens and mice in the blender to feed his hawks. It was often a perverse scene of despair and violence.'

Her comments on animals were just a fraction of her six-minute takedown of her famous family member, who is the son of Robert F. Kennedy.

But the seasoned diplomat, who also had a posting in Japan under Barack Obama, surely knew it would strike hard against RFK, Jr, after his odd experiences with animals emerged during the the presidential campaign.

RFK revealed he once dumped a bear cub carcass in Central Park; admitted to picking up roadkill his entire life; and claimed a parasitic worm ate part of his brain.

Caroline Kennedy also blasted his comments on vaccines and said he had gone on to 'misrepresent, lie and cheat his way through life.' 

She accuses him of being 'addicted to attention and power.'

'Bobby preys on the desperation of parents of sick children, vaccinating his own kids, while building a following hypocritically discouraging other parents from vaccinating theirs.'

She accused him of spreading 'conspiratorial half-truths about vaccines.' 

'In other words, he is willing to enrich himself by denying access to a vaccine that can prevent almost all forms of cervical cancer and which has been safely administered to millions of boys and girls,' she said.

Her video came after the Washington Post reported on her letter to senators, throwing yet another wrench into a tough confirmation process.

On Sunday, the New York Post came out with a blistering editorial arguing against his confirmation and using Trump's own words, calling him a 'Radical Left Lunatic.'

A group founded by former Vice President Mike Pence has run ads opposing him based in part on his support for abortion rights.
