A notice sent to the SCU Board of Trustees didn’t elaborate on the allegations against O’Brien, but the university issued a statement regarding the investigation.

“The SCU Board of Trustees supports the investigation being undertaken by the USA West Provincial of the Jesuits into the exhibited behaviors, consisting primarily of conversations, by Father O’Brien in adult settings which may be inconsistent with established Jesuit protocols and boundaries,” the statement read.

The statement further said that the University takes the accounts seriously, but “at the same time, we fully respect Father O’Brien’s right to a fair and impartial investigation.”
