A push by the Trump administration to end Russia's war on Ukraine appears to make headway, with Kyiv saying Zelenskyy could visit D.C. within days to finalize a deal.

U.S. Army Secretary Dan Driscoll held talks with Russian officials in Abu Dhabi on Monday, a U.S. official told Reuters, the latest effort by President Donald Trump's administration to broker a peace agreement between Russia and Ukraine.

Polish Prime Minister Donald Tusk said “it would be good to know for sure who is the author of the plan,” as tensions over elements that mirror long-standing Russian demands.
