Los Angeles has already approved a gradual increase in wages to $15 an hour by 2020.

Tuesday, a vote is expected that could expand that pay raise to unincorporated areas of LA county.

One of those casting a vote is Supervisor Hilda Solis, who also served as the US Secretary of Labor for several years.
