The U.S. Army may have hindered money-raising efforts for its own national museum by nixing a plan to use revenue from leased federal land to fund the project.

The Army planned to lease out land on Fort Belvoir’s 800-acre Engineer Proving Ground near Interstate 95 but backed off shortly after Rep. Jim Moran, D, and Sen. John Warner, R, sought to introduce legislation blocking the venture. They objected because businesses located on the land would have generated traffic but could not be taxed to help deal with the traffic at the same levels as nearby firms not on federal land.
