(CBS) — Just ahead of Wednesday’s televised debate, campaign officials with two of Chicago’s mayoral candidates are arguing about a clandestine leak of information about another debate Thursday, reports WBBM Political Editor Craig Dellimore.

There is no dispute someone sent Cook County Commissioner Jesus “Chuy” Garcia’s campaign notes and potential questions for Thursday’s debate on ABC 7.

Rival candidate Alderman Bob Fioretti’s campaign issued a press release demanding to know who sent the stuff and how long Garcia had it.

The Garcia campaign says it received the material just a day ago and quickly turned it over to ABC 7, Univision and the League of Women voters, the debate’s organizers. The organizers distributed it to all five campaigns to be fair.

Fioretti campaign advisor Michael Kolenc says it is all troubling and shows the power of the Chicago political machine.

Garcia campaign manager Andrew Sharp says Garcia never looked at the material and he accused the Fioretti camp of implying they did something wrong when in fact they did the right thing.
