CHICAGO -- Federal authorities are investigating Chicago Public Schools CEO Barbara Byrd-Bennett.
It involves a $20 million no-bid contract that was awarded to her former employer, SUPES Academy in Wilmette.
The three-year contract was to train CPS principals who want to become superintendents.
The CPS inspector general's office started investigating it shortly after the contract was signed in 2013.
The U.S.Attorney's office launched its own investigation last year.
Byrd-Bennett has not been accused of any wrongdoing.
Her three year contract with CPS expires at the end of June.
CPS officials have discussed the possibility of appointing an interim CEO until the investigation is complete.
