CHICAGO (CBS) — Former Chicago Police Superintendent Garry McCarthy has been subpoenaed in the Jesse Jackson Jr. divorce case.

The former Congressman and his wife, former Ald. Sandi Jackson, are in the middle of a nasty divorce. The subpoena asks McCarthy to turn over a wealth of information pertaining to a relationship to Sandi — dating back to 2012.

It demands McCarthy turn over records of cash, checks, or property given to Ms. Jackson, including attorney’s fees, groceries, rent or clothing. The subpoena also asks the former superintendent to produce documents detailing what he received from her.

Additionally, Jesse Jackson’s attorneys are seeking social media correspondence, photos, videos, emails and texts between McCarthy and Ms. Jackson.

“He’s so desperate,” Sandi Jackson said of the subpoena.

McCarthy told CBS 2: “I’m not going to comment on anything that stupid.”

Jesse Jackson Jr.’s attorney has alleged Sandi committed “acts” that led to the divorce, but has not elaborated.
