Secretary of State Marco Rubio will receive a private audience with Pope Leo XIV on Thursday, May 7, 2026, at 11:30 a.m., the Vatican announced, in a significant diplomatic development that has left Vice President JD Vance conspicuously excluded from the high-profile encounter. The arrangement marks a dramatic shift in the administration’s Catholic outreach and has intensified speculation about a deepening rivalry between the two prominent Catholic figures in President Trump’s inner circle.
Rubio’s three-day visit to Rome, scheduled from Wednesday through Friday, also includes sessions with Vatican Secretary of State Pietro Parolin and Italian Prime Minister Giorgia Meloni. The devout Catholic who regularly attends Mass will meet with the American-born pontiff one day before Leo marks his first anniversary leading the world’s 1.4 billion Catholics.
The State Department has framed Rubio’s mission in measured terms. “Secretary Rubio will meet with Holy See leadership to discuss the situation in the Middle East and mutual interests in the Western Hemisphere,” a State Department spokesperson said in confirming the trip.
Trump’s Blistering Attacks on the Pope
The Vatican meeting unfolds amid extraordinary tensions between the White House and the Holy See. President Trump stunned many observers by attacking Pope Leo, the first American-born pontiff, after the pope called for peace in the Middle East war and said Trump’s call to destroy Iranian civilization was unacceptable. The president branded Leo as “WEAK on crime, and terrible for foreign policy.”
Trump escalated his rhetoric further on The Hugh Hewitt Show on May 4, accusing Leo of being “fine” with Iran having a nuclear weapon and warning he is “endangering a lot of Catholics and a lot of people.” The pontiff fired back on May 5, saying critics should “do so with the truth,” and flatly rejecting the nuclear claim: “The Church has spoken out against all nuclear weapons for years, so there is no doubt on that point.”
The pope has also publicly criticized Trump’s sweeping crackdown on immigration, drawing further presidential ire. Christians across the world rallied in support of the pontiff in the wake of Trump’s outbursts, and analysts warn the feud could carry real political costs. Polls conducted in March and April 2026 showed growing disapproval of Trump among American Catholics — an ominous warning sign for a president who won a majority of Catholic voters in the 2024 election.
Vance Frozen Out of Papal Talks
Vance, who converted to Catholicism in 2019, had been positioned as the administration’s natural envoy to the Vatican. But with the vice president nowhere on the guest list, the snub is widely interpreted as fallout from the pope’s reported decision to decline Vance’s invitation to the White House.
The decision to send Rubio alone marks a striking reversal from standard diplomatic protocol and has fueled speculation about a growing rivalry between the two Catholic power players in Trump’s orbit. With Leo bristling at Vance’s outreach and Rubio earning the coveted private audience, the Cuban-American secretary of state now appears to hold the upper hand in the administration’s Catholic diplomacy portfolio.
Meloni Caught in the Crossfire
Rubio’s itinerary also includes a Friday morning meeting with Meloni, a session Rubio himself requested, an Italian government source told AFP. The far-right Italian leader has long been considered one of Trump’s closest European allies, but that bond has frayed badly. President Trump insulted Meloni after she defended the Catholic leader, criticizing her as lacking courage.
The president has even threatened to pull U.S. troops from Italy, complaining that Rome “has not been of any help to us” in the Iran war. Italian media have framed this week’s meetings as an attempt to “thaw” relations chilled by Trump’s broadsides.
“Meetings with Italian counterparts will be focused on shared security interests and strategic alignment,” the State Department said.
Cuba and the Western Hemisphere on the Agenda
Cuba looms as another likely topic of discussion at the Vatican. The Holy See has long played an active role in diplomacy on the island, and Rubio — a Cuban-American — has been leading the Trump administration’s efforts to pile pressure on the communist government in Havana. Vatican officials have historically served as quiet brokers in U.S.-Cuba relations, and Rubio’s private audience offers a chance to recalibrate that channel.
For the Vatican, the meeting represents a delicate balancing act: engaging substantively with Washington on global crises while not appearing to capitulate to a White House that has publicly humiliated both the pope and one of Europe’s most prominent Catholic leaders. For Rubio, it is an opportunity to position himself as the indispensable bridge between an angry president and an unyielding pontiff — a role that, until recently, many assumed Vice President Vance would play.
Whether Thursday’s audience produces a genuine thaw or merely papers over deep divisions remains to be seen. But with the vice president sidelined and the secretary of state ascendant, the contours of Trump’s Catholic diplomacy have shifted dramatically — and the rivalry between two of the administration’s most prominent Catholic voices has only intensified.
