U.S. President Donald Trump's envoy, Steve Witkoff, will visit Moscow this week for a new round of talks with Russian President Vladimir Putin about the war in Ukraine, the White House said on Tuesday.

"This statement is very harmful to the Peace Negotiations with Russia," Trump said in a social media post. He said Crimea was lost years ago "and is not even a point of discussion." Zelenskiy on Tuesday reiterated that Ukraine will not recognize Russia's occupation of the Crimea.
