Democratic Gov. Bev Perdue vetoed two bills on Wednesday, including one that would require teachers and state employees to pay a greater cost for their health insurance.
Perdue urged the legislature to return to the negotiating table, saying "now is simply not the time to cut teachers' pay, yet again."
The governor also vetoed a bill that would have given community colleges the option of opting out of federal student financial loan programs.
The GOP leadership said the governor's veto of the health care bill was putting state employees' health care coverage at risk.
"Our bill makes changes very similar to those in the governor's budget," said Senate leader Phil Berger, an Eden attorney. "But with the health plan on the verge of financial collapse, she recklessly chose to cater to her political base."
Perdue has now vetoed four bills in the past two months.
