(CNN) - Oklahoma Gov. Brad Henry endorsed Barack Obama's White House bid Wednesday.
"Senator Obama is uniquely positioned to unite our nation and move beyond the divisiveness and partisan skirmishes that too often characterize politics as usual in Washington,” Henry told The Oklahoman.
Henry, currently serving his second term, had said he did not plan to endorse until the party's convention in late August.
Hillary Clinton won Oklahoma on February 5 with 55 percent of the vote.
Henry is one of the party's 720 superdelegates who will ultimately decide the party's nominee. About 300 remain undecided. (Related: Clinton picks up superdelegate)
