Pope Leo XIV made headlines on May 25, 2026, at the Vatican, where he introduced his inaugural Encyclical Letter titled "Magnifica Humanitas," which addresses the implications of artificial intelligence. This 42,300-word document emphasizes the need for increased oversight on AI, cautioning against its potential to displace jobs, exacerbate inequality, and place decisions about lethal weaponry out of human reach. Alberto Pizzoli captured the moment in a photo for AFP.
Interior Secretary Doug Burgum reignited the ongoing tension between the Trump administration and the Vatican by downplaying Pope Leo's concerns about AI during an interview on Fox Business. He questioned the appropriateness of the pope's engagement in technological critique, stating, "I didn't know that tech editorializing was part of the role of being pope."
In contrast, Vice President JD Vance, who is the highest-ranking Catholic in the Trump administration with ties to Silicon Valley, praised the pope's encyclical as "profound." He highlighted its moral implications as necessary leadership for the church as we enter a new era dominated by AI.
This divergence of viewpoints reveals the complex political landscape President Donald Trump faces as he promotes AI deregulation and its significance in his economic strategy for a potential second term while managing a high-profile disagreement with the first American pope.
Peter Casarella, a theology professor at Duke Divinity School, commented on the situation, noting that Vance seems to be moderating his prior critiques of the pope’s understanding of theology, suggesting an effort to recalibrate their stance.
The timing of Leo's statement coincided with Trump's announcement to postpone an executive order intended to establish a voluntary AI safety review process, which faced backlash from the tech sector. Trump stated that he was concerned about the potential negative impacts of oversight on America's competitive edge against China.
Some within the Catholic community have expressed alarm that unregulated AI could outstrip the ability of policymakers to address issues impacting work, family, and children.
Michael Toscano, director of the Family First Technology Initiative, was emphatic in his support for the pope's call for more ethical standards in AI development, suggesting that the current political climate—with its increasing complexities leading up to the November elections—might soon expose the shortcomings of the administration's approach.
Tensions between the White House and the Vatican have escalated over the past year as Leo has also criticized Trump’s immigration policies, the conflict in Iran, and has chosen not to engage with Trump’s "Board of Peace," advocating instead for a UN-centric approach to global governance.
Trump has retaliated by labeling Leo as "weak on crime" and "detrimental to foreign policy," even sharing an image that likened himself to Jesus attending to a suffering man. Leo, however, has asserted that he has "no fear of the Trump administration."
Adding a layer of complexity, the encyclical was launched in partnership with Christopher Olah, co-founder of Anthropic, a significant player in AI development that opposes unrestricted military use of its technologies. Anthropic did not comment further on the matter.
Paolo Carozza, a law professor at the University of Notre Dame, remarked on the unprecedented nature of the dialogue between the pope and influential figures in tech, suggesting it represents a positive development for many observers.
As these disputes unfold, they could alienate some Catholic voters, an important demographic for Trump. In the 2024 elections, Trump secured 55% of the Catholic vote compared to 43% for Kamala Harris, while in the previous election, Catholics were almost evenly split between Trump and Joe Biden.
Despite tensions, immediate shifts in support among conservative Catholics are unlikely, as many still align with Trump on issues like abortion and religious freedom. However, unresolved conflicts over immigration, warfare, and now AI could prove significant for more moderate Catholic voters, particularly those who are not strongly attached to either political party.
Political scientist Ryan Burge highlighted that the cumulative effects of inflation, gas prices, war, and issues surrounding AI could challenge Trump’s standing among voters who may feel ambivalent about their support for him.
The impact of these dynamics might be particularly pronounced in midterm elections, with Catholic voters possibly influencing key swing districts across states like Long Island, Pennsylvania, and Ohio, where Republicans have gained traction.
Burge advised that the Republican Party must tread carefully in its relationships with various voter blocs, noting that Catholics represent a crucial voting population. He added that Democrats might leverage Leo's warnings in their campaigns, highlighting any negative remarks from Trump regarding the pope as potential campaign fodder in heavily Catholic regions during the next election cycle.
