Top Trump administration officials are meeting Ukrainian negotiators in Florida this weekend, pushing to broker an end to Russia's war in Ukraine and setting the stage for key talks planned this week in Moscow with Russian leader Vladimir Putin.

Zelensky didn't reveal much detail about an updated plan, although he said there needed to be more investment for drones.

Ukraine’s chief negotiator, in an exclusive interview, says conceding sovereign territory is off-limits in peace talks.

"None of us really know what Zelenskyy is like operating solo, because he never has," one expert told NBC News.

Russian President Vladimir Putin said that a US plan to end the war in Ukraine could “form the basis for future agreements” but renewed threats to seize more territory by force unless Kyiv withdraws.

Ukrainian President Volodymyr Zelenskiy will visit French President Emmanuel Macron in Paris on Monday, Macron's office said, as the Ukrainian leader finds himself in the most difficult political and military situation since Russia's invasion in 2022.

The majority of Americans disapprove of Trump's handling of the Russia-Ukraine conflict, as the U.S. tries to broker a deal between the two countries.

Andriy Yermak has played a crucial role in the war with Russia and is Ukraine's lead negotiator in peace talks.
