U.S. President Donald Trump and Ukrainian leader Volodymyr Zelenskyy, in Rome for the funeral of Pope Francis, met one-on-one in a marble-lined Vatican basilica on Saturday to try to revive faltering efforts to end Russia’s war with Ukraine.

It was their first face-to-face meeting since they argued in front of cameras in the Oval Office in February — and comes as efforts intensify to end Russia's war in Ukraine.
