Aaron Schock's defense team says it's been told that the former Illinois congressman is being indicted by a federal grand jury.

Schock's attorney, George Terwilliger, calls the expected charges a "misuse" of prosecutorial power by the Justice Department.

Federal prosecutors in Illinois were expected to announce charges later Thursday.

Schock, a 35-year-old Republican from Peoria, had been under investigation after a spending scandal that included the elaborate remodeling of his Capitol Hill office in the style of the television series "Downton Abbey." He resigned last year from the House of Representatives.
