Bolton told The Sun: "Shortly after Zelensky was sworn in, Putin belittled him to Trump in a phone conversation in ways that I think really affected Trump.
Former US National Security Advisor John Bolton said over five years ago that Trump wasn't Zelensky's biggest fan when he first became president.
VLADIMIR Putin poured poison in Donald Trump's ear about Volodymyr Zelensky the moment the Ukrainian president was sworn in, his ex-aide told The Sun.
Bolton, who served as Trump's National Security Advisor from April 2018 to September 2019, said Putin "belittled" Zelensky on the call.
Bolton believes Trump's scalding remarks last week could be traced back to the call he had with Putin six years ago.
