On Thursday, U.S. Secretary of State Marco Rubio arrived at the Vatican for a private audience with Pope Leo XIV at the Apostolic Palace. This visit aims to mend ties between Washington and the Holy See after weeks of open tension between the pontiff and President Donald Trump.
Rubio, who is a devout Catholic, was welcomed at 11:15 a.m. local time by Bosnian Archbishop Peter Rajic, the newly appointed Prefect of the Pontifical Household. The delegation made its way through St. Peter's Square under tight security before entering the small papal state via the Arch of the Bells, a passage reserved for dignitaries.
Cuba: A Central Topic of Discussion
Amidst the diplomatic strains, the issue of Cuba took center stage during the meeting. On Tuesday, Rubio shared at a White House press briefing his intention to discuss the distribution of humanitarian aid in Cuba through the Catholic Church, criticizing the Díaz-Canel regime for obstructing these efforts.
"We are prepared to send more humanitarian aid to Cuba, but the Cuban regime must allow us to do so," Rubio stated, as reported by AFP. In February 2026, the United States sent six million dollars in aid to Cuba through Caritas Cuba. Additionally, there are nine million dollars earmarked for victims of Hurricane Melissa in eastern Cuba, which Washington wants to channel via ecclesiastical routes, but these efforts are being blocked by the regime.
The Vatican has a well-established history as a mediator between Washington and Havana, having facilitated the rapprochement between Obama and Raul Castro from 2014 to 2016, and played a role in the release of 553 Cuban prisoners under the Biden administration.
As the son of Cuban immigrants who arrived in the United States in 1956, Rubio has led efforts under the Trump administration to apply pressure on the island's communist government.
Backdrop of Trump-Leo XIV Tensions
This visit occurs amidst unprecedented tensions between Trump and the pontiff, sparked by the conflict that the United States and Israel initiated against Iran. On April 7, the pope described Trump's threat to "wipe out an entire civilization" in Iran as "truly unacceptable." Trump retaliated on Truth Social, labeling the pope as "soft on crime" and "terrible in foreign policy," even posting an AI-generated image depicting himself with Christ-like iconography.
The pope stood firm, remarking, "I have no fear of the Trump administration." This week, Trump again lashed out, accusing the pontiff of "endangering many Catholics" by supporting Iran's acquisition of a nuclear weapon. Rubio denied that his trip was driven by this clash, emphasizing that "there is much to discuss with the Vatican," highlighting religious freedom as a common ground between both parties.
A Meeting Described as a "Candid Conversation"
After the papal audience, Rubio also met with Vatican Secretary of State Cardinal Pietro Parolin, who previewed the meeting's tone on Wednesday. "I imagine we will discuss everything that has happened in recent days; we cannot avoid these topics," he stated to journalists, according to AFP.
Parolin confirmed that discussions would cover international issues such as Latin America, Cuba, and Lebanon, summarizing the Vatican's stance in two words: "We will listen." U.S. Ambassador to the Holy See, Brian Burch, characterized the meeting as "a candid conversation." This marks the second meeting between Rubio and Leo XIV; the first occurred on May 19, 2025, when Rubio visited alongside Vice President JD Vance, a day after the inauguration mass of the pontificate. This time, Rubio leads the charge in repairing the relationship with the Holy See.
Following his Vatican visit, Rubio is scheduled to meet with Italian Prime Minister Giorgia Meloni tomorrow, who has defended the pope and faced criticism from Trump, who threatened to withdraw U.S. troops from Italy, Spain, and Germany.
