BOISE, Idaho (AP) — A private prison company being sued by the American Civil Liberties Union amid allegations of violence at an Idaho lockup has shuffled the state's former warden and assistant warden to top posts at two federal prisons.

Phillip Valdez was warden at the Idaho Correctional Center near Boise and has been named assistant warden at the Leavenworth Detention Center in Kansas. ICC's former assistant warden, Dan Prado, has been named to that position at the new Nevada Southern Detention Center.

Corrections Corporation of America announced that Valdez and Prado would no longer lead the Idaho prison after the $155 million lawsuit was filed earlier this year. The ACLU and inmates at the prison claim CCA officials used inmate-on-inmate violence as a management tool.
