President Obama supports a bill sponsored by a pair of congressional Democrats to bump the federal minimum wage to $10.10 an hour, a White House official said Thursday.

Sen. Tom Harkin (D-Iowa) and and Rep. George Miller (D-Calif.) have been pushing a plan to raise the federal minimum wage from $7.25 an hour to $10.10 an hour in increments of 95 cents. Not all Democrats have been on board.

"The President has long supported raising the minimum wage so hardworking Americans can have a decent wage for a day's work to support their families and make ends meet, and he supports the Harkin/Miller bill that accomplishes this important goal," the official said.

"In endorsing a $10 minimum wage, President Obama has taken an important step to grow the economy and  provide support to struggling workers,” said Christine L. Owens, executive director of the National Employment Law Project.
