Pittsburgh Mayor Luke Ravenstahl has given local colleges and universities an ultimatum: Offer a plan to provide $5 million a year in support to the city, or the City Council will vote next week on his proposed 1 percent tuition tax, The Pittsburgh Post-Gazette  reported. The plan for the tuition tax has been opposed by college leaders and students, and is being watched closely by colleges nationwide.  There has been some hope that the idea might be shelved if college offered support in other ways. But the mayor's latest statement does not seem to be going over well in higher ed. Duquesne University President Charles Dougherty, in a statement on behalf of the Pittsburgh Council on Higher Education, said: "Asking universities to fix an underfunded pension fund in return for taking an illegal, counterproductive, and unprecedented tax off the table is unreasonable."
