The meeting at the White House comes after a much-hyped summit between Trump and Putin that saw the U.S. president flex his deal-making skills but achieve no major breakthrough in peace negotiations over Russia’s war against Ukraine.

European Commission President Ursula von der Leyen and NATO Secretary-General Mark Rutte are among those expected to attend.

Trump's stance on ending Russia’s invasion of Ukraine has shifted to align with Russian President Vladimir Putin following their meeting Friday.
