MADISON, Wis. -

Gov. Scott Walker plans to ask the Legislature to freeze tuition at the University of Wisconsin in light of reports that UW has $650 million in reserves.

Walker spokesman Tom Evenson said Wednesday the call for a tuition freeze and possibly other changes will be submitted to lawmakers in a week to 10 days.

The university has been the target of blistering criticism, primarily from Republican lawmakers, following the nonpartisan Legislative Fiscal Bureau memo released Friday that detailed the reserve funds.

UW President Kevin Reilly defended the university during a hearing Tuesday before legislative leaders, saying the reserves were built up to protect themselves as state funding dwindles. He also acknowledged that anger over the accumulated money was, in many ways, justified.
