RICHMOND, Va. (AP) -- -

Sen. Mark Obenshain says he's going to outline his next steps in the nearly knotted race for attorney general.

The Harrisonburg Republican has scheduled a news conference for Wednesday in Richmond. Unofficial state election results show Democratic Sen. Mark Herring with a narrow lead over Obenshain.

After provisional ballots were tallied late Tuesday in Fairfax County, Herring declared himself the winner. Obenshain did not concede, saying he would wait for the state's certification of the Virginia-wide vote. That occurs Nov. 25.

Obenshain did not say whether he would seek a recount.

The State Board of Elections on Wednesday showed Herring with a 164-vote lead.

Obenshain released the following statement on Tuesday night:

"At this stage, we are in the closest statewide election in Virginia history. The State Board of Elections currently estimates a difference of fewer than 200 votes out of more than 2 million votes cast. That's less than 1/100th of a percent difference. With the completion of the canvass of local boards, we have finished two of the three automatic steps of vote counting. The State Board of Elections will now conduct its own review, scheduled to be complete November 25th. We owe it to the people of Virginia to make sure we get it right, and that every legitimate vote is counted and subject to uniform rules. We have seen significant swings in the vote count over the last several days as errors are corrected as a part of the regular canvass process. The State Board of Elections will now conduct its own review and we will await their results. I thank our dedicated election officials who have put in long hours and given great care to their duty. We will make further announcements in the days ahead."
