A bill that would have provided added funding to state and city public colleges and universities was vetoed on Tuesday by Gov. Andrew Cuomo, who cited existing funding agreements in place.

The veto was a disappointment to higher education advocates who had sought the approval of what’s known as a maintenance of effort for the SUNY and CUNY systems.

But Cuomo, in his veto message, said the state has been funding its public college systems at an “unparalleled” level.

“My commitment to funding education at all levels is unwavering,” Cuomo wrote in the veto message. “Collectively, however, these bills would add hundreds of millions of dollars in increased and unbudgeted costs to the state’s financial plan, which will ultimately be shouldered by the state’s taxpayers.”

Cuomo also pointed to looming budget cuts on the federal level, which he said adds to the uncertainty surrounding the state budget.

But supporters of the MOE legislation were unconvinced.

At a time when he has vehemently opposed the Republican tax bill that would devastate New York’s working families and attack universities and students, Governor Cuomo has chosen to veto legislation that would have stabilized funding for New York’s public universities,” said the Professional Staff Congress, which represents CUNY instructors.

“What a missed opportunity! With a signature instead of a veto, the Governor could have shown CUNY and SUNY students that their education is worthy of stable State support. He could have shown the nation that New York is willing to invest in the top-rate public college education that working people need in an economy that is being increasingly rigged for corporations and the ultra-rich.”

The veto was one of several dozen Cuomo issued on Tuesday. He also struck down a bill that would have added a tax credit for TV and film productions that have a diverse writers’ staff.

But while Cuomo said he has concerns with who would benefit from the tax credit, he indicated in the veto message he would direct the Empire State Development Corp. to study whether women and people of color are underrepresented in writers’ rooms in New York productions.
