The chairman of the group's political action committee, Tony Perkins, says O'Donnell will speak at the event Friday afternoon. Perkins says the organization has endorsed O'Donnell and they "applaud her for valiantly defending faith, family and freedom" during her campaign.
O'Donnell ousted nine-term GOP Congressman Mike Castle in Tuesday's primary election to represent Republicans on the ballot in November in the race to fill the Senate seat formerly held by Vice President Joseph Biden.
Other Values Voter Summit speakers include Virginia Gov. Bob McDonnell, former Massachusetts Gov. Mitt Romney and former House Speaker Newt Gingrich.
