President Donald Trump revealed on Wednesday that he had a “highly productive phone call” with Russian President Vladimir Putin about negotiating to conclude the war in Ukraine.

Trump shared on social media that he and Putin desire to stop “the millions of deaths taking place” in the war between Ukraine and Russia which started nearly three years ago. The two chief executives will therefore “have our respective teams start negotiations immediately.”

Trump said that “millions of people have died in a war that would not have happened if I were President, but it did happen, so it must end,” repeating that “no more lives should be lost.”

Secretary of State Marco Rubio, CIA Director John Ratcliffe, National Security Advisor Michael Waltz, and Special Envoy Steve Witkoff will negotiate on behalf of the United States. Trump said he would also call Ukrainian President Volodymyr Zelensky to “inform him of the conversation.”

Trump later posted that he had spoken to Zelensky in a conversation that “went very well” and said he “wants to make peace.” They discussed a “variety of topics having to do with the war.”

Russian Press Secretary Dmitry Peskov said in a statement that the “Middle East settlement, the Iranian nuclear program, and bilateral Russian-American relations in the economic area were talked about during the conversation.” Putin invited Trump to visit Moscow and voiced “readiness to receive American officials in Russia regarding areas of mutual interest.”
