ANNAPOLIS (WUSA9) -- Maryland Governor Martin O'Malley signed the state's new minimum wage law on Monday.
The Maryland Wage and Hour Law phases in increases from the federal minimum wage of $7.25 an hour to $10.10 an hour over a three-year period.
O'Malley signed the bill into law at the Maryland State House in Annapolis.
According to the governor's office, Maryland joins 21 states and the District of Columbia with minimum wage rates higher than the federal level of $7.25 per hour. Maryland and Connecticut will have the highest state minimum wages in the nation once the wage increases to $10.10.
