Fox News host Maria Bartiromo called out former President Donald Trump after he suggested he could end the war on Ukraine in 24 hours because he was impeached for a "perfect phone call" with the country's president, Volodymyr Zelenskyy.

"You said you could end the war in Ukraine in 24 hours," Bartiromo noted in a Sunday interview. "How would you do that?"

Trump referred to the so-called "perfect phone call" pressuring Zelenskyy to find dirt on Joe Biden ahead of the 2020 election.

"I know Zelenskyy very well. I felt he was very honorable because when they asked him about the perfect phone call that I made. He said it was indeed. But he said, it was, he didn't even know what they were talking about," Trump said of his first impeachment.

"Well, that's not gonna be enough for Putin to stop bombing," Bartiromo interrupted.

"No, no, no, no," Trump replied. "I'm not saying that. What I'm saying is that I know Zelenskyy very well, and I know Putin very well, even better, and I had a good relationship very good with both of them."

Trump said he would tell both leaders they had to make a deal to end the war.

"I will have the deal done in one day now," he insisted.
