The chairman of Iowa's Republican Party says he is stepping down following criticism of the Jan. 3 caucus vote count.
In a written announcement Tuesday, chairman Matt Strawn didn't address the caucus count in which a close race led him to first declare Mitt Romney the winner by eight votes. Two weeks later, Strawn initially declined to name a winner when a recount showed Rick Santorum with a 34-vote edge.
Santorum was later declared the winner.
Strawn says his resignation will be effective Feb. 10.
