The president made the phone call, which lasted 20 minutes, to the BBC after conversations about a potential interview to mark one year on since the attempt on his life at a campaign rally in Butler, Pennsylvania.
Asked about whether surviving the assassination attempt had changed him, Trump said he liked to think about it as little as possible.
“I don’t like to think about if it did change me,” Trump said. Dwelling on it, he added, “could be life-changing”.
Having just met with Nato chief Mark Rutte at the White House, however, the president spent a significant portion of the interview expanding on his disappointment with the Russian leader.
Trump said that he had thought a deal was on the cards with Russia four different times.
When asked by the BBC if he was done with Putin, the president replied: “I’m disappointed in him, but I’m not done with him. But I’m disappointed in him.”
Pressed on how Trump would get Putin to “stop the bloodshed” the US president said: “We’re working it, Gary.”
“We’ll have a great conversation. I’ll say: ‘That’s good, I’ll think we’re close to getting it done,’ and then he’ll knock down a building in Kyiv.”
