(CNN) - Mayor Gavin Newsom will veto the city's ban on most McDonald's Happy Meals with toys on Friday.
The mayor has scheduled an event at Fairmount Elementary School at 2:45 p.m. ET, where he will also release a report outlining the city's efforts to combat childhood obesity, his office said.
The San Francisco, California, Board of Supervisors approved the ban on Tuesday.
The ordinance requires McDonald's and other fast-food servings with toys to meet new nutritional standards.
Newsom had indicated he would veto the law. That veto would be meaningless because the board approved the ordinance 8-3, a veto-proof margin. With eight votes, the board could override the veto.
The new law, which San Francisco officials hope other cities will adopt in battling a child obesity epidemic, was a defeat for McDonald's, which led the fight against the measure.
