U.S. President Donald Trump’s special envoy for Ukraine and Russia, retired Lt. Gen. Keith Kellogg, arrived in Kyiv on Monday, a senior Ukrainian official confirmed, amid growing anticipation of a potential shift in Washington’s approach to the war.

Trump recently promised a “major statement” on Russia, expressing frustration with President Vladimir Putin’s continued attacks. Though Trump once praised Putin as a willing negotiator, he has since condemned Moscow’s intensifying strikes on civilians.

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

Trump also confirmed the U.S. is sending Patriot air defense missiles to Ukraine, with the European Union covering the cost. However, the EU cannot directly purchase weapons under its treaties, so member countries are funding them through the European Peace Facility.

Russian drone and missile attacks kill at least 2 in Ukraine

Ukraine continues to face relentless Russian drone and missile strikes, with June recording the highest civilian casualties in three years—232 killed and 1,343 injured, according to the UN.

Republican Senator Lindsey Graham said the war is reaching an “inflection point” as Trump shows renewed commitment. “One of the biggest miscalculations Putin has made is to play Trump,” Graham said.

Talks in Kyiv will focus on defense, weapons, and cooperation, said Andrii Yermak, head of Ukraine’s presidential office.

Meanwhile, NATO Secretary-General Mark Rutte is set to meet Trump and top U.S. officials in Washington.

Russia launched fresh strikes early Monday, killing two in Sumy region, while Ukraine intercepted dozens of drones overnight.
