Speaking to reporters on Friday after his clash with Zelensky in the Oval Office, Trump told reporters "it didn't work out exactly great".
He said Zelensky "overplayed his hand" in the exchange, and repeated the claim that Zelensky is dealing with a "very weak set of cards" in potential peace negotiations.
Trump said Zelensky would be "strong" if the leader signed the US-proposed minerals deal. "He's looking to go on and fight, fight, fight, we're looking to end the death," Trump added.
Asked what the Ukrainian leader needs to do to re-start talks, Trump said "he's got to say 'I want to make peace'".
He then repeated his threat of withdrawing American support: "Either we're going to end it or let him fight it out".
