Bishop Salvatore Cordileone

Bishop Salvatore Cordileone of Oakland, Calif., a leading conservative in the Catholic hierarchy who is set to become the next archbishop of San Francisco, was arrested over the weekend for drunken driving and has apologized “for the disgrace I have brought upon the Church and myself.”

Catholic experts said the arrest was not likely to derail Cordileone’s installation, set for Oct. 4, given that it appeared to be an isolated incident and he apologized so quickly and publicly.

Cordileone, 56, was taken into custody Saturday at 12:26 a.m. after San Diego police stopped his vehicle at a DUI checkpoint near the San Diego State University campus. A native of San Diego, he was booked into the county jail on a misdemeanor charge of driving under the influence and was released later Saturday after posting $2,500 bail.

In a statement on Monday, Cordileone explained that he was having dinner at the home of some friends, along with his 88-year-old mother, who lives near the university. He was driving his mother home after midnight when he was topped by police “and was found to be over the California legal blood alcohol level.”
