NEW YORK (AP) — Monster Beverage is suing San Francisco’s city attorney over demands that the company reduce the amount of caffeine in its energy drinks and stop marketing to minors.

The company, based in Corona, Calif., says it’s being unfairly singled out by City Attorney Dennis Herrera, who late last year had asked Monster to produce documentation showing that its drinks are safe. Since then, Monster says Herrera has asked it to reformulate its drinks and change its labels and marketing materials.
