April 13 (UPI) — President Donald Trump lashed out at Pope LeoXIV over his criticism of the war in Iran, claiming a reason the American was named pontiff was because the Church was trying to curry favor with his administration.

Since being elected the first American head of the Catholic Church in May, Pope Leo has criticized the Trump administration’s policies, particularly its aggressive immigration crackdown and military campaigns. As the war in Iran has continued, the Chicago native has ramped up his criticism of the New York real estate mogul and his administration.

Seemingly in response, Trump on Sunday called the pope “WEAK on Crime and Terrible for Foreign Policy.”

“Leo should be thankful because, as everyone knows, he was a shocking surprise. He wasn’t on any list to be Pope, and was only put there by the Church because he was an American, and they thought that would be the best way to deal with President Donald J. Trump,” Trump said in a statement on his Truth Social platform. “If I wasn’t in the White House, Leo wouldn’t be in the Vatican.”

Amid the conflict, Pope Leo has repeatedly called for an end to the war in Iran and other conflicts, most often without mentioning the warring parties or their leaders by name.

In seemingly pointed remarks in late March, the pope said God “does not listen to the prayers of those who wage war, but rejects them.” Then early this month, the pontiff, speaking in Italian, described Trump’s threat to destroy “the whole Iranian civilization,” as “truly unacceptable!”

In his late Sunday statement, Trump said he preferred Leo’s eldest brother Louis Prevost, a noted supporter of the president’s far-right nationalist Make America Again movement.

“Leo should get his act together as Pope, use Common Sense, stop catering to the Radical Left and focus on being a Great Pope, not a politician,” Trump said.

“It’s hurting him very badly and, more importantly, it’s hurting the Catholic Church!”

Catholic Americans constituted a major electoral bloc in Trump’s 2024 election victory. According to the Pew Research Center, about 55% of Catholic voters cast ballots for Trump compared to 43% for his Democratic challenger, former Vice President Kamala Harris.

The statement comes as pressure mounts on Trump over the war in Iran, which was launched jointly with Israel on Feb. 28. During the current two-week cease-fire, U.S. efforts to secure a permanent end to the war are ongoing as calls from Democrats and critics for his ouster grow louder.

“The deranged and disgusting post from Trump attacking Pope Leo should certainly help him appeal to the more than 50 million Americans who identify as Catholics. Perhaps this will convince JD Vance to invoke the 25th Amendment to remove Trump from office,” Rep. Pramila Jayapal, D-Wash., said in a statement referring to the vice president, who is Catholic, and his ability to invoke a constitutional mechanism that could lead to Trump’s removal from the White House.
