ROME (AP) — U.S. Vice President JD Vance extended an invitation to Pope Leo XIV to visit the United States during a meeting at the Vatican on Monday ahead of a flurry of U.S.-led diplomatic efforts to make progress on a ceasefire in Russia’s war in Ukraine.

Vance gave the first American pope a letter from U.S. President Donald Trump and the first lady inviting him. The Chicago-born pope took the letter and put it on his desk and was heard saying “at some point,” in the video footage of the meeting provided by Vatican Media.

In the days since his May 8 election, Leo has vowed “every effort” to help bring peace to Ukraine. He also has emphasized his continuity with Pope Francis, who made caring for migrants and the poor a priority of his pontificate.
