Aboard a charter flight from Algiers to Yaounde on Wednesday, Pope Leo XIV pressed forward with an 11-day, four-nation Africa tour as an escalating public dispute with President Donald Trump played out on social media thousands of miles away, testing the first American pope’s ability to keep his planned program at the center of a journey that Washington has tried to reshape from afar.
Leo, traveling with a Vatican delegation and roughly 70 accredited journalists in a tightly managed press pool, did not take reporters’ questions on the five-hour flight to Cameroon. He delivered brief remarks in English about his just-concluded Algerian visit — the first papal trip to that country — without addressing Trump directly.
The public exchange pits an American president against the first American pope in a sustained dispute over the Iran war and the proper reach of religious authority, with millions of American Catholics watching both men claim moral standing on the same set of facts.
How the dispute developed
The conflict escalated this week when Trump posted on Truth Social accusing Leo of being soft on crime, cozy with the left, and of owing his papacy to Trump, according to an Associated Press report from inside the papal press pool. Trump’s posts came in response to Leo’s calls for peace in connection with the Iran war and Leo’s statement that Trump’s threat to annihilate Iranian civilization was “truly unacceptable.”
Leo addressed the controversy directly on April 13, during the flight from Rome to Algiers. Coming to the back of the plane to greet traveling journalists, he said he was merely preaching the Gospel when he called for peace and criticized war, and said he did not fear the Trump administration, according to AP correspondent Nicole Winfield, who was aboard.
Vice President JD Vance, a Catholic convert, separately said Leo should “be careful” when speaking about theology.
Wednesday’s measured response
On the longer Algiers-to-Cameroon flight, Leo did not take questions. His remarks were delivered entirely in English — a choice that reporters aboard noted against the backdrop of the overnight exchanges with Washington — and focused on what he had seen in Algeria.
Leo praised the “goodness,” “generosity,” and “respect” shown by Algerian authorities, noting that the government had provided “a full military aerial escort of the papal plane through Algerian airspace.” He described his visit to the Great Mosque in Algiers as a demonstration that “although we have different beliefs, we have different ways of worshipping, we have different ways of living, we can live together in peace.”
He invoked his spiritual inspiration, St. Augustine of Hippo, whose legacy he had honored during a stop in Annaba — the ancient city of Hippo where the theologian once served as bishop. St. Augustine’s message of “searching for God, searching for truth, building bridges and seeking unity and community,” Leo said, was “something which the world needs to hear today and that together we can continue to offer in our witness as we continue on this apostolic voyage.”
He did not mention Trump or the Iran war by name.
The press pool and what it offers
The Vatican’s traveling press pool, which on this trip includes roughly 70 accredited journalists, offers a form of access unusual for any world leader: reporters pay to board the papal charter and have the opportunity to question a sitting pope in real time — but only when he chooses to come to the back of the plane.
Pope Francis set a formative precedent in 2013 on his first papal journey, to Rio de Janeiro, when a reporter asked him about a purportedly gay priest and he replied, “Who am I to judge.” The line became one of the most widely quoted of his papacy and illustrated the stakes of in-flight exchanges.
On this trip, with Leo at the center of a dispute that has no modern equivalent — an American president in public conflict with an American pope — the press pool has watched each leg of the Africa journey for signs of what Leo will say next.
Angola is the next stop on Leo’s tour.
