Pope Leo XIV

The U.S.-born pope was writing in his first encyclical, a sweeping and eagerly anticipated manifesto.

History’s first U.S.-born pope, whose family history includes both enslaved people and slave owners, delivered the apology in his first encyclical, “Magnifica Humanitas” (Magnificent Humanity), which was released Monday.

The pope will join leading Catholic theologians and an Anthropic co-founder Monday to release a landmark encyclical.

Leo hit out at “unscrupulous people and organizations” behind decades of mafia-linked toxic waste dumping.

The visit kicked off a series of day trips that Leo will be making over the next few weeks, up and down the Italian peninsula.

The audience comes at a fraught time between Washington and the Holy See, after weeks of presidential criticism from the first American pontiff.

The president accused the pope of "endangering a lot of Catholics and a lot of people" for criticizing the Iran war.

The Chicago-born pontiff said his comments about the world being "ravaged by a handful of tyrants" were prepared "weeks ago."

Some spent the night on the ground, battling mosquitoes, to stake out their spot for the pontiff's Mass in the economic capital of Cameroon.

The incident comes amid a brewing feud between President Donald Trump and the first American pontiff over the war with Iran.
