Trump vs. Leo XIV Leaves Rubio Cleaning Up
Marco Rubio’s Vatican trip is now damage control: Trump’s attacks on Leo XIV are turning a diplomatic meeting into a test of White House discipline.
Donald Trump is creating the leverage problem for his own secretary of state. Reuters reported that Marco Rubio was set to meet Pope Leo XIV at the Vatican on Thursday, after Trump intensified criticism of the first American pope by accusing him of being soft on Iran and warning that the pontiff was endangering Catholics (
Reuters). The Washington Post/AP said Rubio’s trip was intended partly to ease tensions between Washington and the Holy See, just as the administration’s Iran war policy and migration stance have collided with the pope’s public interventions (
The Washington Post).
The power dynamic: Trump sets the tone, Rubio absorbs the fallout
Trump is using the pope as a domestic political target. On Hugh Hewitt’s show, he said Leo XIV “prefers talking about the fact that it is okay for Iran to have a nuclear weapon,” adding that the pope was “putting a lot of Catholics and a lot of people in danger,” according to Reuters and Le Monde (Reuters; 
Le Monde). The pope has not called for Iran to get a bomb; he has criticized war, urged negotiation, and framed his comments as church teaching, not electoral politics, Le Monde and La Croix both reported (Le Monde; 
La Croix).
That leaves Rubio in a narrow lane. He is a practicing Catholic, he needs the Vatican to stay engaged on religious freedom and conflict diplomacy, and he has to explain away Trump’s rhetoric without openly contradicting him. That is a bad place for any secretary of state, and especially for one who already gets tasked with translating Trump’s blunt force on Europe, NATO and the Middle East into something survivable for allies. On 
United States politics, this is the familiar pattern: the president speaks to the base; the secretary of state cleans up the signal.
Who benefits, who loses
The immediate beneficiary is Trump’s domestic political message: he gets to present himself as defending order, security and American power against a pope who criticizes war and deportations. But the strategic loser is the administration’s diplomacy. The Vatican is not a minor venue; it is a moral megaphone with access in Europe and the Global South, and Leo XIV’s status as an American pope gives his critique unusual resonance. Reuters noted that Trump has already attacked the pope before, while Italian officials including Giorgia Meloni and Antonio Tajani have pushed back, calling the language unacceptable and unhelpful (Reuters; La Croix).
For Rubio, the visit is now less about Vatican outreach than about proving he can still manage allies after Trump’s latest escalation. If he leaves Rome with only a courtesy photo and no sign of de-escalation, the White House will have shown that it can still undercut its own diplomats in real time.
What to watch next
Watch whether Rubio and the Vatican issue even a modestly warm readout, and whether Trump keeps attacking Leo XIV after the meeting. The next real test is whether the administration can stop turning the pope into a political foil before the Vatican hardens its line on Iran and immigration.
