• Marco Rubio is set to meet Pope Leo at the Vatican amid Trump's criticisms.
• The meeting is the first between a Trump cabinet member and the pontiff in nearly a year.

• The Pope firmly rejects accusations concerning nuclear weapons, emphasizing peace.

U.S. Secretary of State Marco Rubio arrived at the Vatican for a meeting with Pope Leo XIV on Thursday, May 7. This meeting comes amidst ongoing tensions as President Donald Trump has engaged in a series of disparaging comments towards the pontiff regarding the U.S-Israel war on Iran. Rubio, who is also Trump's national security adviser, is expected to have a closed-door discussion lasting about half an hour at the Vatican's Apostolic Palace, which is the first meeting between the pope and any Trump cabinet official in almost a year, according to Reuters and Channel News Asia.

Pope Leo has notably become a target for Trump's criticisms after voicing his opposition to the U.S.-Israeli war on Iran, which the president has described as endangering many Catholics. Trump falsely claimed on Monday that the pope was in favor of Iran acquiring nuclear weapons, prompting a strong rebuttal from the pontiff, who asserted, "The mission of the Church is to preach the Gospel, to preach peace," and emphasized that the Church has long opposed nuclear arms, as reported by Al Jazeera and Reuters.

The U.S. ambassador to the Holy See, Brian Burch, indicated that the discussions between Rubio and Pope Leo are expected to be "frank." Additionally, the Vatican Secretary of State Cardinal Pietro Parolin acknowledged the unique nature of this encounter, highlighting the diplomatic effort involved in facilitating conversations amid the current political climate. Rubio is scheduled to also meet with Italian Prime Minister Giorgia Meloni, who has publicly supported Pope Leo in light of Trump's remarks, according to Channel News Asia and Al Jazeera.

Pope Leo, who marks his first year as the leader of the 1.4 billion-member Catholic Church this Friday, has become increasingly vocal on various global challenges, including a recent assertion that the world is "being ravaged by a handful of tyrants." Although these comments resonate with the current political tensions, Leo has clarified that they were not directed specifically at Trump. As such, the meeting with Rubio not only seeks to address critical international issues like religious freedom and Cuba but also aims to ameliorate the strained relationship between the Vatican and the U.S. administration, according to Reuters and Channel News Asia.
