COLUMBUS -- The president of the Ohio Senate says he's committed toward working to give the governor's income tax plan full consideration.

The written statement from Sen. Tom Niehaus comes a day after he had expressed wariness about the proposal.

Gov. John Kasichwants to hike oil and gas drilling taxes and link proceeds to an income-tax cut. His plan would raise the severance tax on oil and gas extraction to 4 percent in two or three years. Income tax reductions would deepen as proceeds rose.

Niehaus told The Columbus Dispatch Thursday ( ) that economic uncertainty would make him "a little more cautious about committing that money at this point."

The senator on Friday called Kasich's proposal "thoughtful" and said in the statement he looked forward to working with him.
