In the latest move in the interstate fight over the U.S. Space Command’s permanent headquarters, Alabama Republican U.S. Rep. Robert Aderholt has introduced legislation to block the federal government from building, buying or leasing public buildings “based on the legality or availability of abortion.”

Space Command’s startup headquarters is located in Colorado Springs, Colo., and the state is lobbying to make it the command’s permanent home. Abortion is legal in Colorado and part of that state’s argument to keep the command is that Alabama’s strong anti-abortion laws will block the legal rights of female headquarters staff and the spouses of male staff members.

Redstone Arsenal in Huntsville, Ala., was ranked No. 1 in the Pentagon’s official base site selection process based on such comparisons as available housing, cost of living, quality schools and job opportunities for spouses. But current Alabama law bans abortion except in cases with a “serious health risk to the pregnant woman.” There are no exceptions for rape or incest.

Aderholt’s bill is the latest response by Alabama’s congressional delegation to the Pentagon delay in naming the permanent headquarters location. U.S. Rep. Mike Rogers, chair of the House Armed Services Committee, is holding up the Air Force’s ability to move already budgeted funds to cover funding shortfalls until the base dispute is settled.

Republican U.S. Rep. Dale Strong of Huntsville, who also argued for the move in the House Armed Services Committee, is one of Aderholt’s co-sponsors for the new legislation.
