Trump's Ukraine Envoy on whether US will give up on peace, inside a Putin phone call, and dealing with Trump's character

Keith Kellogg has perhaps the hardest job of all in the Trump administration. The retired general is the US President's Special Envoy for Ukraine, putting him right at the forefront of the American effort to end Russia's invasion - travelling between Washington, Kyiv, Turkey, the Middle East, attempting to reconcile the very, very different demands of Vladimir Putin, Volodymyr Zelenskyy, and an increasingly impatient Donald Trump. And it has not been an easy ride. He was the first American official to meet with Zelensky after Trump called him a 'dictator' back in February; he was just a metre away when the pair later had that extraordinary shouting match in the Oval Office. And this week, he's been tasked with diffusing escalating tensions after Ukraine's audacious drone attack on Russian war planes. So it was quite a moment for our US Correspondent Dan Rivers to sit down with him for an extended interview, to discuss whether there is really ANY path to peace any more, and what it's been like dealing with Donald Trump behind the scenes.
