President Obama will sign an executive order formally raising the minimum wage for federal workers during an event Wednesday at the White House.

The move, first announced during the State of the Union address, will raise the minimum wage for federal workers hired under new contracts to $10.10 per hour. It will also raise the tipped minimum wage to $4.90 from $2.13 per year, with an escalator clause that will increase that amount in subsequent years.

Obama will also press Congress to match the executive order with an equivalent hike to the federal minimum wage, the White House said Tuesday. According to a source familiar with the event, the president will appear alongside workers who are paid at or just above the federal minimum wage of $7.25 per hour.

“The president is using his executive authority to lead by example, and will continue to work with Congress to raise the minimum wage for all Americans by passing the Harkin-Miller bill,” the White House said in a statement. “The bill would raise the Federal minimum wage for working Americans in stages to $10.10 and index it to inflation thereafter, while also raising the minimum wage for tipped workers for the first time in over 20 years.”

Obama has made the populist initiative one of his major talking points following his State of the Union address late last month.
