The Rt. Rev. Marc Andrus, Episcopal Bishop of California and an invited guest for the installation of Archbishop-designate Salvatore Cordileone, was not allowed to be seated. He was escorted to a basement room at St. Mary's Roman Catholic Cathedral and detained by an usher until the time the service began, whereupon Bishop Andrus left the cathedral. More information will be forthcoming as it is available.

He was with other ecumenical guests before the service, all of whom were seated while he waited. Read more here.
