(KTRS) – Members of the Illinois Congressional delegation say they may block funding for the National Geospatial-Intelligence Agency’s new facility in north St. Louis.

The Senate passed a defense bill that would set aside money to buy the land and design the facility. But the House Appropriations Committee cut all money used to purchase the land and halved the amount of money for design expenses. The Illinois opponents say that the environment study of the St. Louis site was flawed and say the site near Scott Air Force Base is the best option.

The NGA is supposed to finalize their decision June 2.
