The outcome of their call is expected to influence the president’s discussions with his Ukrainian counterpart, Volodymyr Zelensky, on Friday over the prospects of the U.S. providing a powerful new weapon system.

Donald Trump hit Russia's two biggest oil companies with sanctions in his latest sharp policy shift on Moscow's war in Ukraine.

The Kremlin denied Tuesday that it was holding up President Donald Trump’s latest push to end the war in Ukraine, and insisted it had not changed its demands ahead of possible talks. Trump had announced that Russia and the United States' top diplomats would meet this week, with his own summit with Vladimir Putin to follow in Budapest, Hungary.

President Volodymyr Zelensky told Axios that President Trump's new sanctions will hurt the Russian war machine, but Ukraine still needs long-range missiles to force Vladimir Putin to make peace. Why it matters: It's been a head-spinning two weeks for Zelensky.
