'Disappointed' Trump says Zelenskyy hasn't read latest plan to end Russia's war

President Donald Trump has said he is "disappointed" with Ukraine's Volodymyr Zelenskyy, who he said had not read the latest plan to end Russia's war.

Trump's criticism adds to mounting U.S. pressure on Kyiv as Zelenskyy prepared to meet Monday with top European leaders, amid fears on the continent that Washington was pushing a deal that was favorable to Russia.

Trump's team held talks with Ukrainian officials in Miami after flying to the Kremlin with a revised version of the peace proposal, but the push from Washington has so far failed to find a breakthrough. The Kremlin has not publicly supported a plan and has stuck to its hardline demands.

Speaking to reporters Sunday, Trump said he was “a little bit disappointed that President Zelenskyy hasn’t yet read the proposal.”

It was unclear exactly which version of the peace plan Trump was referencing.

“His people love it. But he hasn’t. Russia is fine with it,” said Trump, on the Kennedy Center Awards’ red carpet in Washington.

“You know, Russia... I guess would rather have the whole country when you think of it. But Russia is, I believe, fine with it, but I’m not sure Zelenskyy is fine with it. His people love it, but he hasn’t read it.”

Despite Trump’s suggestion that Moscow was “fine” with the most up-to-date version of the deal, the Kremlin has indicated otherwise.

Putin’s foreign policy aide Yuri Ushakov said Sunday the American side would have to make “radical changes” to the draft on “some issues.”

There was no immediate reaction from Zelenskyy, but his top negotiator said he would brief the Ukrainian leader on Monday following the talks in Miami.

"The primary task of the Ukrainian team was to obtain from the American side complete information about their conversation in Moscow and all drafts of current proposals in order to discuss them in detail with the President of Ukraine," Rustem Umerov said in a post on X.

“We are working as intensively as possible,” Umerov added.

NBC News has reached out to Zelenskyy’s office for a response to Trump's comments.

Zelenskyy said late Sunday that he had spoken with Trump’s special envoy Steve Witkoff and son-in-law Jared Kushner, who had held five hours of talks with Putin in Moscow last week.

“The American envoys are aware of Ukraine’s core positions, and the conversation was constructive, though not easy,” Zelenskyy said.

The Ukrainian leader is in London to rally support from his European allies, as leaders on the continent scramble for a seat at the negotiating table.

Trump approved a 28-point peace plan to end the war last month, but it appears to have undergone several changes after intense pushback from Kyiv and Europe.

It originally called for Ukraine to cede territory, including land it currently holds; reduce the size of its army and promise to never join NATO, among other demands that were largely seen as favoring Russia.

While Zelenskyy has stayed open to negotiating peace with Trump, he has previously made it clear that safeguarding Ukraine’s sovereignty was his primary objective in any deal.
