Pope Leo XIV’s oldest brother defended his choice to share a social media post referring to California Rep. Nancy Pelosi as a “drunk c-t,” saying Monday, “I wouldn’t have posted it if I didn’t kind of believe it.”

Louis Prevost did not apologize for the foul-mouthed comment hurled at the former House speaker while predicting to Piers Morgan what President Trump’s first encounter with the next pope will be like.

The in-depth interview with the pontiff’s brother and self-proclaimed Donald Trump supporter comes as media outlets report on a slew of Facebook posts that Prevost, 73, either shared or wrote before his brother — formerly known as Cardinal Robert Francis Prevost — was named Pope Francis’ successor.

One offensive message was a video uploaded by Prevost from another social media user of Pelosi in 1996 discussing tariffs with a commentary attacking her, including using the c-word.

“Well, I posted it, and I wouldn’t have posted it if I didn’t kind of believe it,” Prevost said on “Piers Morgan Uncensored” before he expressed a bit of regret.

“However, I had no idea what was coming this soon, and I can tell you, since then, I’ve been very quiet, biting my tongue at some of the stuff that is out there on social media, because I don’t want to create waves that don’t need to be there because I’m a MAGA type and I have my beliefs,” he added. “I don’t need to create heat for [Leo], he’s going to have enough.”

While Louis Prevost conceded that Leo is not as conservative as he is, he argued that the pope will not support homosexual marriage or women priests, because he is not “woke.”

“I don’t know that I would even go that far to say he is woke,” he said when asked by Morgan.

“I don’t think he is going to go, pull the church hard left,” Prevost also said. “I think he’s going to be down the middle.”

He stated that, like Francis, he expects Leo would welcome homosexual individuals into the church but will not campaign for same-sex marriage. He also stated that he may appoint women to advisory posts inside the church, but will not let them to become priests.

When Morgan inquired about his brother’s potential connection with Trump, Prevost hinted at a minor disagreement, even if he does not believe they would be “enemies.”
