RALEIGH – A chief architect of a North Carolina tax overhaul plan that’s been rejected by other Senate Republicans and Governor Pat McCrory says he’s resigned as co-chairman of the Senate Finance Committee.

Senator Bob Rucho of Mecklenburg County wrote Thursday to Senate leader Phil Berger saying he had submitted his resignation as chairman effective earlier this week.

The Associated Press obtained a copy of the letter, in which Sen. Rucho says he and Berger have a “fundamental disagreement” on the most effective model of tax reform and how to manage the legislation.

Sen. Rucho co-authored a plan that would greatly expand the services subject to the sales tax while lowering income and corporate tax rates.

But Gov. McCrory said he preferred a plan by House Republicans, and Berger offered an alternative to Sen. Rucho’s plan.
