President Trump and European leaders met for a one-of-a-kind summit at the White House on Monday to push toward a peace deal between Russia and Ukraine. But by the end of a marathon day of meetings, details on what such an agreement might entail remained elusive.

"I like the concept of a ceasefire for one reason, because you'd stop killing people immediately... But we can work a deal where we're working on a peace deal while they're fighting." President Trump walked back on his previous comments where he suggested "severe consequences" for Russia if Russian President Vladimir Putin didn't agree to a ceasefire before a meeting with Ukrainian President Volodymyr Zelenskyy and other European and NATO leaders.
