The document is scheduled to be filed by Friday, the Chicago Sun Times reported. Jackson and his wife, former Chicago Alderman Sandi Jackson, are scheduled for sentencing July 1.
Jackson's lawyers, in a motion Monday, said the sentencing memorandum will include information about Jackson's medical problems and those of a relative, the Chicago Tribune reported.
"In addition, Mr.Jackson plans to submit letters from two medical professionals regarding his medical condition," the lawyers said. "Disclosure of these materials would unnecessarily expose to the public intimate details of Mr. Jackson's and his family member's medical diagnoses and treatment."
The lawyers said prosecutors do not object to sealing some of the sentencing material, although they want to reserve the right to ask for it to be opened later.
Jackson, son of the civil rights leader, surfaced last year in the Mayo Clinic where he was being treated for bipolar disorder. He pleaded guilty to using campaign funds for personal expenses while his wife admitted evading income taxes.
