Voters in Arizona, Colorado and Maine voted Tuesday to raise minimum wages for over two million workers. The wage will be raised to $12 an hour.

Washington voted to raise the state minimum wage to $13.50. But therse wages won't fully phase in until 2020.

The Economic Policy Institute says legislative minimum wage increases passed earlier this year in California, New York, Oregon, the District of Columbia and roughly a dozen cities and counties helped millions more workers.
