SAN FRANCISCO — San Francisco District Attorney George Gascon says he has "grave concerns" about Ross Mirkarimi's (meer-kah-REE'-mees) ability to manage the Sheriff's Department.

Mirkarimi found out late Tuesday that he will get to keep his job despite his conviction in a domestic violence case involving his actress wife.

Four members of the Board of Supervisors voted to allow him to remain in office. His removal would have required nine votes of the 11-member board.

But Gascon said in a statement released Wednesday that he is asking Mirkarimi to recuse himself from work related to the custody, supervision, safety and rehabilitation of domestic violence offenders.

Gascon also asked that an administrator be named to oversee work related to domestic violence cases within the Sheriff's Department.
