KYIV, Ukraine (AP) — U.S. President Donald Trump’s special envoy to Ukraine and Russia met with Ukraine President Volodymyr Zelenskyy in Kyiv on Monday, as anticipation grew over a possible shift in the Trump administration’s policy on the three-year war.

Trump last week said he would make a “major statement” on Russia on Monday. He was due to meet with NATO Secretary-General Mark Rutte in Washington. Rutte also planned to hold talks with U.S. Defense Secretary Hegseth and Secretary of State Marco Rubio, as well as members of Congress.

Trump made quickly stopping the war one of his diplomatic priorities, and he has increasingly expressed frustration about Russian President Vladimir Putin’s unbudging stance on U.S-led peace efforts.

Trump has long boasted of his friendly relationship with Putin, and after taking office in January repeatedly said that Russia was more willing than Ukraine to reach a peace deal. At the same time, Trump accused Zelenskyy of prolonging the war and called him a “dictator without elections.”

But Russia’s relentless onslaught against civilian areas of Ukraine wore down Trump’s patience. In April, Trump urged Putin to “STOP!” launching deadly barrages on Kyiv, and the following month said in a social media post that the Russian leader “ has gone absolutely CRAZY!” as the bombardments continued.

"I am very disappointed with President Putin, I thought he was somebody that meant what he said,” Trump said late Sunday. “He’ll talk so beautifully and then he’ll bomb people at night. We don’t like that.”

Zelenskyy said he and Trump’s envoy, retired Lt. Gen. Keith Kellogg, had “a productive conversation” about strengthening Ukrainian air defenses, joint arms production and purchasing U.S. weapons in conjunction with European countries, as well as the possibility of tighter international sanctions on the Kremlin.

“We hope for the leadership of the United States, because it is clear that Moscow will not stop unless its ... ambitions are stopped by force,” Zelenskyy said on Telegram.
