The White House says it only found out about the postal service's decision to end Saturday delivery a day ago and is still reviewing it.
But, Press Secretary Jay Carney acknowledged after questioning, the White House called for Saturday closings in its budget last year.
But Carney said that it was part of a "series of proposals for reform of the Postal Service that would put it on much more firm financial ground." The proposal cleared the Senate but not the House.
"It is true that as part of these reforms that we proposed, that that change in delivery service was included," Carney said. "But the overall package is what's important here, because .. our view was that there need to be a series of actions taken to help make the Postal Service more financially sound."
He said he couldn't yet say if the adminstration agrees that the Postal Service has the authority to make the move without congressional authorization.
