University of California President Janet Napolitano says she’ll hold off on raising tuition for the next six months. But it’s only temporary relief. Napolitano says costs will go up after that, possibly as much as 28 percent over the next five years, unless the UC system gets more taxpayer dollars. Governor Jerry Brown, on the other hand, says Napolitano needs to freeze tuition and cut costs if she wants more government funding. The conflict came to a head in Sacramento recently, with lawmakers calling on both sides to do some explaining.
