Washington (CNN) – President Barack Obama will issue an executive order in "the next 10 days or so" to create a bipartisan commission on reducing the federal deficit, White House Press Secretary Robert Gibbs said Thursday.
Obama previously said he would use an executive order to set up the panel after the Senate rejected a bill sponsored by both Democrats and Republicans to do so.
The White House has cited opposition to the bill by several Republican senators who co-sponsored the legislation as an example of political game-playing in Washington.
The commission, composed of congressional Democrats and Republicans, will be asked to come up with recommendations for reducing the deficit. The recommendations are expected to include a mix of tax increases and spending cuts, including possible reduced benefits from entitlement programs such as Social Security.
Some Republicans have warned they could decide against serving on the panel because they fear it will be a vehicle for raising taxes.
Asked about possible GOP reluctance, Gibbs said, "We hope that Republicans - many of whom supported this commission before they had to vote on this commission and then they magically didn't support this commission - we hope that when the president signs this executive order and announces his picks for this commission, that they will demonstrate their seriousness in dealing with an issue of this magnitude by taking part in that commission."
Gibbs also said Obama remains opposed to raising taxes for Americans earning less than $250,000 a year, but the president would not "prejudge" the commission or its work.
"The president doesn't believe our economic growth ... should be predicated on raising taxes on middle-class families," Gibbs said. "But that being said, the president's just not going to get in the game of prejudging the outcome of a commission that ... hasn't been set up and hasn't met."
