Just five days before Christmas, President-elect Donald Trump announced he is appointing outspoken conservative and president of CatholicVote Brian Burch to serve as the U.S. ambassador to the Vatican. 

The Vatican, also known as the "Holy See," is the center of the Roman Catholic Church, which is led by Pope Francis. There are roughly 52 million Catholics in the U.S. 

Burch, a father of nine, is an outspoken supporter of the president-elect. His organization, CatholicVote, a conservative activist group, issued its first presidential endorsement in Trump’s favor this year.

Catholic voters across the country swung massively toward Trump in the 2024 election, contributing to his surprise blowout victory on election night.

In his post announcing the nomination, Trump credited Burch for his significant gains among Catholic voters in November, saying that Burch "represented me well during the last Election, having garnered more Catholic votes than any Presidential Candidate in History!"

"I am pleased to announce that Brian Burch will serve as the next United States Ambassador to the Holy See," said Trump. "Brian is a devout Catholic, a father of nine, and President of CatholicVote. He has received numerous awards, and demonstrated exceptional leadership, helping build one of the largest Catholic advocacy groups in the Country."

"Brian loves his Church and the United States - He will make us all proud," the president-elect said. "Congratulations to Brian, his wife Sara, and their incredible family!"

Burch responded to his nomination by posting on X: "To God be the glory."

"Words cannot express my gratitude to all those that have helped me achieve this nomination," said Burch. "I am deeply honored and humbled to have been nominated by President Trump to serve as the United States Ambassador to the Holy See."

He thanked his family, the CatholicVote team and gave special credit to his recently deceased father who, he said, "taught me to love the Church and the blessings and responsibilities of being a citizen of the U.S."

"The Catholic Church is the largest and most important religious institution in the world, and its relationship to the United States is of vital importance," said Burch. "I am committed to working with leaders inside the Vatican and the new Administration to promote the dignity of all people and the common good. I look forward to the confirmation process and the opportunity to continue to serve my country and the Church."

CatholicVote also responded to the announcement, saying the group is "immensely proud" of Burch and that his nomination "is a testament to the importance of Catholics to the United States."

"Under Brian's leadership, CatholicVote has launched influential campaigns exposing violence against Catholic churches and uncovering government overreach targeting Catholics and pro-life advocates," the group said. "Beyond his professional work, Brian is a devoted husband and father of nine children. His commitment to family life informs his passion for building a culture that upholds the dignity of every human person and supports the central role of families in society." 

The new Trump administration will have several Catholics in high-ranking positions, including Vice-president JD Vance, Secretary of State nominee Marco Rubio, Health and Human Services Secretary nominee Robert F. Kennedy Jr. and border czar Tom Homan. 

The position of ambassador to the Holy See requires Senate confirmation.

The White House announced that President Joe Biden will head to Italy next month for a public meeting with Pope Francis in Vatican City before his term comes to an end.

Biden accepted the invitation to visit Vatican City during a phone call with Pope Francis Thursday, according to the White House. 

White House press secretary Karine Jean-Pierre said Thursday that Biden would meet with Italy's Prime Minister Giorgia Meloni and President Sergio Mattarella during the overseas trip. The four-day trip is planned for the second week in January, and the meeting between Biden and Pope Francis will occur in front of an audience on Jan. 10. 

"President Biden will have an audience with the Pope and discuss efforts to advance peace around the world," Jean-Pierre said Thursday. "He will also meet with Italy’s leaders to highlight the strength of the U.S.-Italy relationship, thank Prime Minister Meloni for her strong leadership of the G7 over the past year, and discuss important challenges facing the world." 

Italy's position as president of the G7 countries, a position that rotates annually, will come to an end in the new year. The G7 is a cohort of the world's largest advanced economies.

Biden's trip to meet with Pope Francis will come shortly after the Vatican begins its Holy Year on Dec. 24, a centuries-long tradition that occurs every 25 years, during which pilgrims travel to Rome to visit holy sites and receive forgiveness.  

Biden is only the nation's second Catholic president, after John F. Kennedy. He has met with popes, including Francis, throughout his political career. The trips have also been reciprocated by Francis, who made his first formal visit to the U.S. when Biden was vice president.

Biden last met with Pope Francis in June, during which the pair discussed both the war in Israel and the war Russia is waging against Ukraine. The leaders reportedly emphasized the urgent need for a ceasefire in Gaza and the need to cement a hostage deal during their talks. They also spoke about the ongoing humanitarian impacts of Russia's war against Ukraine, according to the U.S. embassy in Italy. 

The pair met in 2021 as well, which was only the second time a U.S. president other than Kennedy had met with a pontiff. During the private talk, Biden reportedly lauded Francis's leadership "in fighting the climate crisis, as well as his advocacy to ensure the pandemic ends for everyone through vaccine sharing and equitable global economic recovery."

One area where the two leaders' viewpoints notably diverge is abortion, however. Due to Biden's pro-choice stance, many critics, including Catholic bishops, questioned early on in his presidency whether Biden could continue receiving Holy Communion. But following the June meeting at the Vatican, Biden said that Francis expressed support for Biden to be allowed to continue receiving the sacrament.

Biden's trip in the final month of his presidency is expected to be his last overseas.

It will mark a rare occurrence, according to the Associated Press, which noted that the last president to travel overseas during the final month of his presidency was fellow one-term President George H.W. Bush. Bush traveled to Moscow and Paris on diplomatic missions to shore up a nuclear treaty and discuss the Bosnian war that was taking place at the time with France's then-president, according to historical records from the State Department.
