Pope Leo XIV is encouraging some of the wealthiest U.S. Catholics to keep on giving to support his charitable works. The Chicago-born Leo met with members of The Papal Foundation. The organization is a major funder of papal development projects in the developing world. Leo thanked the members for their generosity.  Over the past four decades, foundation grants have totaled more than $270 million. The audience confirmed how the election of the first U.S.-born pope has invigorated American Catholics and their donations.
