While Ukraine's Zelensky was speaking, some of the other European leaders in Washington DC were also talking to media.
Let's check in first with the Nato Secretary General, Mark Rutte. He describes today's meetings as "very successful" and called Trump a "pragmatic peacemaker" in an appearance on Fox News.
"He's putting pressure, but he's also looking for ways to solve this," Rutte says of Trump.
He says opening up the conversation with Putin was important, and that they're working towards a trilateral meeting with Russia, the US and Ukraine.
Today, the main focus was security guarantees, and leaders will be working on those measures over the next few days, he says.
