A plan to block spending for a proposed expansion of the Army's Pinon Canyon training site in southeast Colorado has passed in the U.S. House.

The proposal passed Friday but still has to make it through the Senate.

Representatives Marilyn Musgrave and John Salazar of Colorado had presented the proposal as an amendment to a defense spending bill.

The amendment would bar the military from using money in its 2008 budget to extend land holdings in southeastern Colorado and block funding for an environmental impact study of a proposal to nearly triple the 368-square-mile training site.

Doug Lamborn, who represents the Colorado Springs area that is home to several military installations, was the lone Colorado representative voting against the proposal.
