San Francisco supervisors today gave final approval to an ordinance requiring elected officials to reimburse the city for police security costs when campaigning outside the state.

The measure was introduced by Supervisor Ross Mirkarimi, who has said it “focuses on disclosure, transparency and accountability.”

In addition to reimbursement, the law would require the Police Department report security costs to the supervisors.

The board passed the legislation by a 7-3 margin, but Mayor Gavin Newsom has said he will veto it.

Newsom and police Chief George Gascon have expressed concern that requiring city officials to reimburse the city for security might present a safety risk if they decide to go without it.

Gascon last year disclosed that the city spent nearly $2.1 million to protect Newsom, visiting dignitaries and other city officials.
