Secretary of State Marco Rubio arrived at the Vatican on Thursday for a diplomatic visit focused on stabilizing relations between Washington and the Holy See. Meeting first with Pope Leo XIV and later with Cardinal Pietro Parolin, the Vatican secretary of state, Rubio addressed public friction caused by President Donald Trump’s repeated social media attacks on the first American-born pope regarding the ongoing Iran war. Over the course of the two-and-a-half-hour visit, both sides coordinated public messaging designed to underscore the strength of their partnership despite the cross-Atlantic political noise.
The U.S. State Department said in a post-meeting statement that Rubio and Parolin discussed “ongoing humanitarian efforts in the Western Hemisphere and efforts to achieve a durable peace in the Middle East.” The statement added that the discussion “reflected the enduring partnership between the United States and the Holy See in advancing religious freedom.” In a separate statement regarding Rubio’s audience with the pope, State Department spokesperson Tommy Pigott said the two discussed the situation in the Middle East and the Western Hemisphere. “The meeting underscored the strong relationship between the United States and the Holy See and their shared commitment to promoting peace and human dignity,” he said.
The Vatican’s readout echoed the American side’s emphasis on stable relations, saying that “the shared commitment to fostering good bilateral relations between the Holy See and the United States of America was reaffirmed.” The Vatican statement noted that the two sides exchanged views on current events, placing “particular attention to countries marked by war, political tensions, and difficult humanitarian situations, as well as on the need to work tirelessly in favor of peace.”
The diplomatic encounter came after weeks of escalating rhetoric that threatened to strain the traditional alliance. Tensions began when Trump lashed out at Leo on social media last month, claiming the pope was soft on crime and terrorism because of his comments on the administration’s immigration and deportation policies, as well as his calls for a ceasefire in Iran. Following the president’s attacks, Leo said during an address that God does not listen to the prayers of those who wage war. The friction intensified when Trump posted a social media image appearing to liken himself to Jesus Christ, a post he later deleted after public backlash and for which he has refused to apologize to the pope.
Cardinal Parolin, who met with Rubio on Thursday after the pope’s audience, had previously publicly defended the pontiff against the president’s remarks. “Attacking him like that or criticizing what he does seems a bit strange to me, to say the least,” Parolin said Wednesday in remarks made on the eve of the secretary’s visit.
Rubio told reporters Thursday that Trump’s recent criticisms were rooted in his opposition to Iran potentially obtaining a nuclear weapon, which Rubio said could be used against millions of Catholics and other Christians in the region. Leo has never suggested Iran should obtain nuclear weapons; the pope clarified late Tuesday that the Catholic Church “for years has spoken out against all nuclear weapons, so there is no doubt there.” Addressing the president’s accusations directly, Leo said, “The mission of the church is to preach the Gospel, to preach peace. If someone wants to criticize me for announcing the Gospel, let him do it with the truth.”
By Thursday’s meetings, public tensions appeared to have eased, marked by a traditional diplomatic exchange of gifts. Rubio presented Leo with a small crystal football paperweight bearing the State Department seal, joking about the pope’s known allegiance to the Chicago White Sox. “What to get someone who has everything?” Rubio said as he handed over the gift. Leo presented Rubio with a pen made of olive wood — “olive being of course the plant of peace,” Leo said — accompanied by a coat of arms emblem and a picture book of Vatican artworks.
Beyond the Vatican, Rubio’s diplomatic itinerary included meetings scheduled for Friday with Italian Prime Minister Giorgia Meloni and Foreign Minister Antonio Tajani. Those conversations are expected to be complex; both Italian leaders have strongly defended Pope Leo against Trump’s attacks and have publicly criticized the Iran war as illegal, drawing the president’s ire. Trump has also recently criticized Meloni and other NATO allies for what he described as a lack of support for the Iran campaign, and has announced plans to withdraw thousands of American troops from Germany in the coming months.
Cuba emerged as another central topic of the Rome visit. The Holy See has expressed concern regarding the Trump administration’s threats of potential military action in Cuba following the January ouster of Venezuelan President Nicolás Maduro. Trump has suggested on multiple occasions that Cuba could be “next” once regional conflicts de-escalate, and has floated the idea of Middle East-deployed naval assets returning to the United States via Cubon waters. Rubio, the son of Cuban immigrants and a longtime critic of the island’s government, addressed the humanitarian dimensions of the standoff. “We gave Cuba $6 million of humanitarian aid, but obviously they won’t let us distribute it,” Rubio said. “We distributed it through the church. We’d like to do more.”
Analysts observing the visit noted that the diplomatic mission served multiple objectives. Giampiero Gramaglia, former head of Italy’s ANSA news agency, told the Foreign Press Association that he doubted Rubio was acting solely as a conciliator for the president. “I doubt Rubio has the role of conciliator for Trump,” Gramaglia said. “I have the perception that Rubio’s mission is more about himself,” noting the secretary’s political standing as a prominent Catholic Republican ahead of upcoming midterm elections and the 2028 presidential race.
The Rev. Antonio Spadaro, undersecretary in the Vatican’s culture office, suggested in an essay this week that Washington’s goal was recognition rather than conversion. “Washington has come to acknowledge — implicitly but legibly — that (Leo’s) voice carries weight in the world that cannot simply be dismissed,” Spadaro wrote. He characterized the visit as “a semantic corrective to a narrative of frontal conflict with the church,” indicating that the Holy See views the diplomatic intervention as a necessary stabilization of a heated public narrative.
