OKLAHOMA CITY (AP) - An election official says provisional ballots did not change the unofficial outcome in a House of Representatives race where a Democrat won by three votes.

Democrat Dan Arthrell had a three-vote lead over Republican Katie Henke after Tuesday's special election. Tulsa County Election Commission Secretary Patty Bryant tells The Associated Press that four provisional ballots were determined to be from qualified voters.

She says Arthrell and Henke each received two additional votes. That leaves Arthrell with a 1,418-1,415 lead over Henke. Bryant said the results will be certified at 5 p.m. Friday unless there is a challenge to the ballots or a request for a recount.

Oklahoma Republican Party Chairman Matt Pinnell has said a recount will be requested. Neither he nor Henke immediately returned phone calls for comment.
