The D.C. Council is scheduled to take a preliminary vote on increasing the District of Columbia's minimum wage to $11.50 an hour, one of the nation's highest.
Tuesday's vote comes after similar minimum wage hikes approved by lawmakers in suburban Montgomery and Prince George's counties.
Democratic Mayor Vincent Gray supports raising the minimum wage from its current $8.25 to $10 an hour, but not higher. The council and the mayor clashed earlier this year on raising wages for workers at Wal-Mart and other big-box stores.
The minimum wage bill already has enough support to override a potential mayoral veto. Supporters say raising the minimum wage will allow low-wage workers to benefit from the city's prosperity, while opponents worry it will hurt the job market.
