Story highlights Governor said St. Louis ordinance to raise minimum wage would "kill jobs"

New law overriding minimum wage will go into effect August 28

(CNN) While many cities raised their minimum wage over the past weekend, St. Louis will soon see a 23% decrease.

A new Missouri law will go into effect August 28 that will override the city's minimum wage and lower the hourly rate from $10 to $7.70, which is the state's standard.
