Carper and Boxer said: "The Senate's transportation bill contains a small technical drafting error that affects the Congressional Budget Office's score of the bill. The House could easily fix this error and send the bill back to the Senate, which has voted overwhelmingly in favor of an extension of transportation programs only through the end of the year without pension smoothing. There is still no question that the Senate bill takes the most responsible path toward shoring up the Highway Trust Fund in the long-term. The Senate has already corrected a much more drastic error in the House's bill - one that could have blown an $11 billion hole in the federal budget - by unanimous consent. The House now has the choice to do its part to follow the Senate's lead and make a routine technical correction or take us down a path toward more short-term extensions that will cost taxpayers a great deal more in the long run."
