Inspector general sues former aldermanic candidate for flouting subpoena related to campaign finance probe

Inspector General Joe Ferguson is suing a former aldermanic candidate for defying a subpoena related to a campaign finance probe.

In the lawsuit filed Monday in Cook County Circuit Court, Ferguson alleges that Theresa Siaw has failed to turn over documents or testify in an ongoing investigation into the alleged misconduct of an unnamed city official.

Siaw lost in February’s election to incumbent Ald. Roberto Maldonado, who represents the 26th Ward.

The suit alleges that Siaw has failed to turn over documents or speak with Ferguson’s office since she was called to testify on March 19. Ferguson said his office has already interviewed three people in connection with the investigation and received documents from various parties.

Siaw’s attorney, James Nally, initially objected to the inspector general’s subpoena in a letter dated March 15, according to the suit. Nally claimed in the letter that Siaw would not appear for a meeting because she is not subject to Ferguson’s jurisdiction.

Nally did not respond to requests for comment.

Since receiving the letter, Ferguson has tried and failed to meet with Siaw on several occasion, according to the suit, which seeks Siaw’s compliance with the subpoena.
