In March 2026, Facebook posts spread a rumor that U.S. President Donald Trump and Pope Leo XIV, the first American pope, argued over the ongoing U.S.-Israel war on Iran.
According to the post, Leo criticized the war after Trump and evangelical leaders shared a "prayer for war" at the White House. This supposedly launched a debate in which Trump said, "Sit down — you're just the Pope, mind your own business!" and Leo allegedly responded, "Power may be great, but the responsibility before conscience and the future of humanity is even greater."
Here is an excerpt:
Donald TRUMP SLAMS Pope Leo XIV: "Sit down — you're just the Pope, mind your own business!" — But the Pope's response leaves the entire room stunned
Tensions erupted after Pope Leo XIV issued a strong moral warning from the Vatican about what he called a "prayer for war" at the White House. Earlier, a group of evangelical leaders had gathered in the Oval Office, laying hands in prayer for Donald TRUMP and blessing his confrontation with Iran — an image that immediately sparked intense controversy.
The Chicago-born pope did not hold back. He firmly rejected the display with a message that quickly captured global attention:
"War is not sacred; only peace is sacred, because it is the will of God."After a few seconds of heavy silence, TRUMP responded sharply, insisting that he would not allow religious leaders to interfere with America's national security decisions. He added that praying for the country and its soldiers was "completely legitimate and necessary."
The claim was also shared to groups elsewhere on Facebook. Each post linked out to a blog and directed readers to it for more information.
There was no evidence supporting this story's reality, despite text in the blogs claiming the exchange made international news. Additionally, the posts and blogs had all the hallmarks of AI-generated stories commonly shared over Facebook. Therefore, we have rated this claim as false.
The posts spreading the false rumor linked to advertisement-filled blogs where readers could supposedly read the whole story; three posts linked above ultimately linked to two blogs, as one linked to the same blog as another. Both blogs reused the same words and images.
The blogs claimed, "News outlets across the world carried the story, and political analysts debated the significance of the exchange for weeks." Yet multiple searches for the story yielded no credible news reports on the subject. Not only does this contradict the blogs' claim about the story's coverage, but it's unlikely that not even American mainstream media wouldn't cover a conflict between two of the most powerful Americans in the world.
Stories shared to Facebook without evidence, written in this style and linking to advertisement-filled blogs, are usually created with artificial intelligence tools with the goal of making money by driving traffic to these blogs.
Evidence from the posts they were AI-generated
When concerning political figures, these stories often feature a calm and steady figure shocking people into silence in contrast with a more energized, louder figure arguing with them. AI writing frequently overuses em dashes to separate two contrasting halves of a sentence. For example: "Many present sensed that the moment had moved beyond ordinary political disagreement — it had become a confrontation between power and conscience." The text of the blog post included other examples, such as: "Pope Leo XIV's challenge was not just a personal rebuke to Donald Trump—it was a challenge to all political leaders who wielded power."
Another commonality between these AI-generated stories is that they tend to use stock imagery of their subjects. For example, the people sharing the Leo vs. Trump claim posted the story alongside unrelated images of the two leaders. By not having an image of the two individuals actively engaged in the debate, the story lacks another piece of proof that could support it.
The story itself had some inconsistencies that further suggested it was fake.
At the beginning of the story, the Facebook post says Leo issued a warning from the Vatican after Trump held a "prayer for war" with evangelical leaders at the White House — two locations separated by an ocean. Without establishing how much time had passed or whether the individuals were supposed to be at the Vatican, the White House or elsewhere, the story then describes the pair debating each other in the same room. The pope's words "seemed to stop the room in its tracks" and in the blog post they made "the room [grow] quiet once more."
The blog post had another major inconsistency: "In the weeks and months that followed, the world continued to watch the fallout from this historic moment." The U.S. and Israel began the Iran war on Feb. 28, 2026, and Facebook posts sharing the story were posted March 12, 2026. That's less than two weeks since the start of the war, making it impossible for months to have passed since this confrontation over the war.
Finally, one of the blog posts archived content with months written in Vietnamese. Pages and ad-tech firms based in Vietnam frequently spread AI-generated content over Facebook to cash in through the system of driving traffic to advertisement-filled blogs.
What has really happened
This particular story was loosely based on reality, even if it wasn't true.
On March 5, 2026, White House Deputy Chief of Staff Dan Scavino shared a video of faith leaders praying with Trump at the White House. The prayer was not explicitly a "prayer for war," but many of the faith leaders prayed over Trump and "for U.S. success in the war against Iran," according to Baptist News Global.
At the same time, Leo has made clear that he opposes the war. On March 15, Leo called for a ceasefire. That same day, the The Washington Post published a story about how the pope leaned on allies to more directly criticize the U.S. for its role in starting and carrying out the war.
Leo has not directly singled out Trump for his particular role in the war as of this writing.
