Obama appeared at a Costco wholesale store in suburban Maryland to push his plan to raise the minimum wage from $7.25 to USD 10.10 an hour.
"The economy's been growing for four years now. Corporate profits, stock prices have all soared, but wages and incomes or ordinary people haven't gone up in over a decade," Obama said.
Polls show that a majority of Americans support the idea of raising the minimum wage but the plan remains unlikely to pass Congress because Republicans oppose it, fearing it could hamper small business and jobs growth.
"That's why I firmly believe that it's time to give America a raise."
