U.S. Secretary of State Marco Rubio is scheduled to meet with Pope Leo at the Vatican on Thursday, according to a Vatican source, in a high-stakes diplomatic encounter occurring amidst escalating criticism of President Donald Trump’s rhetoric towards the Pontiff and ongoing international conflicts.
Diplomatic Undertakings Amidst Friction
The anticipated meeting marks the first known in-person engagement between Pope Leo and a U.S. cabinet official in nearly a year. A senior source close to the Pope’s schedule, who spoke on condition of anonymity as they were not authorized to discuss the matter, confirmed the meeting is expected to take place on Thursday.
Pope Leo, known for his increasingly assertive public statements, has recently emerged as a prominent critic of the U.S.-Israeli-led war in Iran. This stance follows his earlier critiques of the Trump administration’s stringent anti-immigration policies.
President Trump has publicly criticized Pope Leo multiple times via social media in April, notably calling the Pontiff “terrible” during the Pope’s four-nation tour of Africa. These public exchanges have drawn significant attention and criticism from across the political spectrum.
Background of U.S.-Vatican Relations
Secretary Rubio last met with Pope Leo, who is the first American Pope, in May 2025. At that time, Rubio was accompanied by Vice President JD Vance. Both U.S. officials attended the new Pope’s inaugural Mass in St. Peter’s Square and held a private meeting with him the following day.
This upcoming meeting comes just days before Pope Leo marks his first anniversary as pontiff on Friday.
Broader Diplomatic Objectives
Italian national dailies La Repubblica and Corriere della Sera had previously reported on Sunday that Rubio would visit Italy for a series of meetings, including discussions with the Vatican’s lead diplomatic official, Pietro Parolin. However, these reports did not confirm whether a meeting with Pope Leo himself would occur.
The U.S. State Department, the Vatican press office, and an Italian government spokesperson have not yet provided immediate responses to inquiries regarding these reports.
Further reports from Italian newspapers suggest that Secretary Rubio is also slated to hold discussions with Italy’s foreign and defense ministers. This trip appears aimed at de-escalating recent tensions between the United States and Italy, particularly following President Trump’s sharp criticism of Italian Prime Minister Giorgia Meloni, a key European ally, last month.
It remains uncertain whether Rubio will also have an opportunity to meet with Prime Minister Meloni during his visit.
European Strategic Realignments
The Secretary of State’s trip to Italy occurs in the wake of the Pentagon’s announcement on Friday regarding the drawdown of 5,000 U.S. troops from Germany, the largest U.S. military base in Europe. This strategic shift underscores growing strains in transatlantic relations, exacerbated by disagreements over the Iran war and tariff disputes.
Italy hosts a significant U.S. military presence, with approximately 13,000 active-duty soldiers stationed across six bases at the close of 2025, making it one of the European countries with the largest contingent of U.S. forces.
Looking Ahead
The meeting between Secretary Rubio and Pope Leo is expected to set a tone for future diplomatic engagements between the U.S. administration and the Vatican, particularly concerning global conflicts and humanitarian policies. Observers will be watching closely for any shifts in dialogue or policy following this encounter, as well as its impact on broader U.S.-European relations and Italy’s role within NATO.
