Illinois Gov. Bruce Rauner speaks at a news conference in the James R. Thompson Center’s 16-story glass-paneled atrium Tuesday, Oct. 13, 2015, in Chicago. Rauner announced he wants to hold a public auction to sell the Thompson Center, which houses state government offices in downtown Chicago, calling the building “ineffective” and a “very wasteful, very inefficient use of space.” He said selling the building and moving state workers elsewhere could save the state between $6 million and $12 million annually.
