“I am eager to take on this new opportunity at this critical time for the RNC and the party,” Pinnell said.
“The success of the state parties will be crucial to developing and implementing a solid ground game, and ensuring Republican victories in the coming elections.”
During Pinnell's tenure as chairman in Oklahoma, Republicans made major gains in registration, regained the Governor's Mansion, picked up seats in the state House and Senate and captured the one congressional seat that had been held by a Democrat.
Last year, Pinnell presided over a fractious state convention as supporters of Ron Paul's presidential candidacy fought with those supporting Mitt Romney. There also was some friction between the Paul supporters and other state party members at the national convention in Florida.
A graduate of Oral Roberts University, Pinnell has worked on state and federal campaigns in Oklahoma.
