MASCOUTAH, Ill. — Members of Illinois’ congressional delegation are appealing to the head of the National Geospatial-Intelligence Agency in support of Scott Air Force Base’s bid to host its new facility. This week, U.S. Sens. Dick Durbin and Mark Kirk and other Illinois congressmen wrote a letter to NGA Director Robert Cardillo, urging him to select a 182 acre site in St. Clair County as the location of the agency’s new $1.6 billion campus. The two-page letter was meant to show there’s “unified support for the proposal from the bipartisan group representing communities across Illinois,” according to a news release issued Wednesday by Durbin’s office.
