O’Brien gave the service at Cathedral of St. Matthew the Apostle, one of the most prominent Catholic churches in Washington, in January for Biden, who is the nation’s second Catholic president, as well as Vice President Kamala Harris, their families and elected officials before the inauguration ceremony at the U.S. Capitol.

O’Brien also presided over services for Biden’s inaugurations as vice president.

The priest has known Biden’s family for about 15 years, according to the university. O’Brien was then serving at Georgetown University, another Jesuit college. O’Brien has been president of Santa Clara University since July 2019.

Sobrato’s statement, posted Monday to the university’s website, did not specify the allegations against O’Brien but said the trustees “support those who came forward to share their accounts.”

Sobrato said that while O’Brien is on leave, the priest will be cooperating with the independent investigation, with conclusions to be shared with the Santa Clara University Board of Trustees. O’Brien didn’t immediately respond to a request for comment.

Tracey Primrose, spokeswoman for the Jesuits West Province, which is overseeing the investigation, did not elaborate on the investigations to The Mercury News.

“Jesuits are held to a professional code of conduct, and the Province investigates allegations that may violate or compromise established boundaries,” Primrose told the newspaper.

Primrose did not immediately respond to The Associated Press’ request for comment Thursday night.

O’Brien joined the Society of Jesus in 1996, according to the university, and was ordained to the priesthood in 2006.
