Ukrainian President Volodymyr Zelenskyy has called for a three-way summit with Donald Trump and Vladimir Putin at a moment aerial strikes between the warring sides have been escalating for several consecutive days. "If Putin is not comfortable with a bilateral meeting, or if everyone wants it to be a trilateral meeting, I don't mind. I am ready for any format," Zelensky said Tuesday, in comments which were published Wednesday.

Zelensky said he's ready for a "Trump-Putin-me" meeting, but simultaneously called for Washington to slap more sanctions on the Kremlin. "We are waiting for sanctions from the United States of America," the Ukrainian leader said. And Trump's response?... "If I think I'm close to getting a [peace] deal, I don't wanna screw it up by doing that," he told reporters at the White House.

Reporter: What's stopping you from imposing sanctions on Russia? 

Trump: If I think I'm close to a deal, I don't want to screw it up. Let me tell you: I'm much tougher than those you're talking about. You have to know when to use it. I think it would hurt the deal.
