U.S. President Donald Trump said on Sunday that he thinks Ukrainian President Volodymyr Zelenskyy wants to make a peace deal with Russia.

The White House said their discussion was “very productive” and that more details would be released later. The meeting lasted about 15 minutes inside St. Peter’s Basilica at the Vatican just before they took their seats for the outdoor funeral service. Zelenskyy said “good meeting” on social media after the funeral.
