Marco Rubio met with Pope Leo XIV in Rome on Thursday in a high-level diplomatic engagement held against the backdrop of strained relations between the Vatican and the White House over the war in Iran and criticism of U.S. foreign policy.
The meeting took place as tensions continue to grow between the Vatican and President Donald Trump’s administration, following repeated remarks by the pope condemning the humanitarian impact of the conflict in Iran and questioning the moral framing of military operations.
According to the U.S. State Department, Rubio and the pope discussed developments in the Middle East and broader geopolitical issues affecting the Western Hemisphere.
The Vatican has not released a detailed statement on the meeting, but officials confirmed that the talks covered international security and humanitarian concerns.
Diplomatic Meeting in Rome
Rubio’s visit to Rome marks one of the most sensitive diplomatic exchanges between Washington and the Vatican in recent years.
The talks come at a time when the pope has taken a more visible role in speaking out against global conflicts, particularly the war in Iran, which has drawn widespread international concern over civilian casualties and regional instability.
The State Department said the discussions were “constructive” and focused on shared interests, including peace efforts and regional stability. However, the meeting also underscored underlying tensions between the two sides, particularly over how the United States justifies its military involvement abroad.
Pope Leo XIV has previously criticized world powers for what he described as “the normalization of war language,” urging restraint and renewed diplomatic engagement.

His comments have drawn attention in Washington, where officials have defended U.S. policy as necessary for regional security.
Strained Vatican-White House Relations
Relations between the Vatican and the White House have become increasingly complicated since Trump returned to office. The pope has been openly critical of the administration’s rhetoric on military intervention, particularly its use of religious language to justify strikes linked to the Iran conflict.
In response, Trump and senior officials have defended their approach, arguing that U.S. actions aim to prevent further escalation and protect allies in the region. The disagreement has created visible friction, with both sides maintaining formal diplomatic channels while expressing opposing views on the war.
Rubio’s meeting with the pope is seen by analysts as an attempt to stabilize communication and avoid a deeper diplomatic rift. While neither side has indicated a breakdown in relations, public criticism from the Vatican has added pressure on Washington’s diplomatic efforts.
Why This Matters
The meeting between Rubio and Pope Leo comes at a critical moment in global diplomacy, as the war in Iran continues to reshape international alliances and test traditional diplomatic relationships.

The Vatican has historically played a soft-power role in conflict mediation, often urging ceasefires and humanitarian protections. Its increasingly direct criticism of major powers signals a more active stance in global political debates, particularly on issues involving war and civilian suffering.
For the United States, maintaining working relations with the Vatican remains important for broader diplomatic engagement, especially in regions where the Catholic Church has significant influence.
