U.S. Reps. Steve Pearce, R-N.M., and Ben Ray Lujan, D-N.M., say House approval is needed to get the bill to the president's desk. Pearce and Lujan spelled out their request in a letter to House leaders on Wednesday.
The legislation was introduced by U.S. Sen. Jeff Bingaman, D-N.M. The Senate has already voted unanimously in favor of the bill.
