MADISON, WI (WTAQ) - Wisconsin Lieutenant Governor Rebecca Kleefish says she won’t be challenging any of the recall petition signatures filed against her. She told the Government Accountability Board her deadline of next Monday doesn’t give her enough time for her campaign to finish its review. Governor Scott Walker’s campaign said the same thing before his deadline, last Monday. An estimated 845,000 signatures were on the petitions filed in the effort to recall Kleefisch. The GAB’s deadline for verifying if there were enough signatures is March 19. Recall supporters collected about three times as many signatures as they needed, leading to the verification process.
