A once-abandoned Illinois prison in Thomson, in northwestern Illinois, is on track to house hundreds of federal inmates.
Illinois spent millions to build a then state-of-the-art correctional center in 2001; but budget cuts meant it never actually opened.
More than a decade later, the federal government bought it.
Some 90 minimum security inmates arrived this summer; more are expected.
U.S. Senator Dick Durbin, a Democrat, says that's the latest information he's received, following a meeting with the head of the US. prisons bureau.
