More than 100 federally contracted workers are expected to stage a rally Wednesday to call for a higher wage.
The rally will be hosted by the Large Retail Accountability Living Wage Coalition.
The group wants President Obama to guarantee a living wage to federally contracted workers. Many workers are employed by restaurants and retailers housed inside federal buildings.
This is the latest in a string of protests by service workers at federal buildings.
A similar rally was held in July when federally contracted concessions workers at Union Station walked off their jobs and demanded a "living wage." And back in May, about 200 federally contracted workers staged strikes around D.C. to protest their low wages. Workers protested outside the Reagan Building, the American History Museum and Columbus Circle at Union Station.
At all of the rallies, speakers called on President Obama to issue an executive order, forcing companies with federal contracts to pay a living wage.
The group also plans to deliver more than 250,000 signatures to the White House in support of the measure.
The rally kicks off at 11 a.m.
Recently, the fight for a living wage in the District hit a road block when Mayor Vincent Gray vetoed a bill that would've required large retailers to pay their employees $12.50 an hour.
