was sitting down with Francis in his private study in the Apostolic Palace. Among the four was Bransfield's cousin, Monsignor Brian Bransfield, secretary-general of the U.S. Conference of Catholic Bishops.

Bishop Bransfield had been investigated for an alleged groping incident in 2007 and was implicated in court testimony in 2012 in an infamous Philadelphia priestly sex abuse case. He strongly denied ever abusing anyone and the diocese said it had disproved the claims. He continued with his ministry until he offered to retire, as required, when he turned 75 last week.

The Vatican said Francis accepted his resignation Thursday and appointed Baltimore Archbishop William Lori to take over Bransfield's Wheeling-Charleston diocese temporarily. Lori said in a statement that Francis had also instructed him to "conduct an investigation into allegations ofsexual harassment of adults against Bishop Bransfield."

No details of the allegations were revealed and his diocese said it had "no idea" where Bransfield was after the Vatican ordered him to live outside the diocese.

Lori set up a hotline for potential victims to call, said the Vatican had instructed him to make the investigation public, and vowed to conduct a thorough study into what he said were "troubling" claims against Bransfield, who was a major fundraiser for the Vatican via the Pennsylvania-based Papal Foundation.

The revelation was the latest twist in an incredible turn of events in the U.S. church that began with the June 20 announcement that one of the most prestigious U.S. cardinals, Theodore McCarrick, had been accused of groping a teenage altar boy in the 1970s.
