The government wants a chance to argue that former U.S. Rep. Aaron Schock of Illinois should be held in contempt of court for failing to turn over documents.
Assistant U.S. Attorney Timothy Bass says a public official "cannot seal his official records and withhold them from the prosecuting authorities on a plea of constitutional privilege against self-incrimination."
Schock's lawyers have said they are disclosing reams of documents. A hearing on the privacy issue is set for Aug. 28.
Authorities are investigating Shock's spending and relationships with donors. The 34-year-old Peoria Republican resigned from Congress March 31 after reports about his "Downton Abbey"-style Capitol office redecorating and other spending.
