VATICAN CITY, ROME — Amid already heightened tensions sparked by former U.S. President Donald Trump’s public rebuke of Pope Leo XIV’s anti-war stance, U.S. Secretary of State Marco Rubio announced Friday that his closed-door discussions with the pontiff yielded a constructive, productive exchange. Speaking to assembled reporters on the grounds of the Vatican immediately after the hour-long meeting, Rubio characterized the encounter as a “very good meeting” that laid clear ground for mutual understanding between the U.S. government and the Holy See.
