LA CROSSE, Wis. -

La Crosse's city council president is challenging a recall petition filed against her.

Audrey Kader is challenging 186 of the 252 signatures collected on the recall petition.

The city clerk says the majority of those signatures list 702 Franciscan Way as an address. That’s the mailing address for the student union at Viterbo University where all the students mailboxes are located.

Kader says the students should have listed the specific dorm address not mailing address. Kader also says some of the signatures are from out of the district and there is at least one duplicate.

The group leading the recall effort has until Monday at 5 p.m. to file a written rebuttal.
