In my view, DJT's anger towards Zelenskyy that was reignited at the Oval Office meeting is deeply rooted in Zelenskyy’s refusal to dig up ‘dirt’ on Biden at DJT's request— or else lose U.S. support — in order to help DJT’s 2020 re-election and to smear Biden’s campaign.
DJT has scapegoated Zelenskyy for not only losing the 2020 election to Biden, but also for his first impeachment for ‘shaking down’ Zelenskyy.
