The call with Vladimir Putin came as Ukrainian President Volodymyr Zelensky said publicly he wanted to discuss weapons supplies with President Trump.

Trump’s call with Putin was scheduled for today at 10 a.m. ET, with a subsequent conversation with Zelensky on Friday. Trump has previously expressed hope that the talks could result in a ceasefire, but his attempts at negotiations between Russia and Ukraine have failed to yield significant progress.

The U.S. president urged Russia’s leader to quickly end the war in Ukraine, according to a Kremlin briefing on the hourlong call.
