WASHINGTON (AP) — Republican presidential hopeful Herman Cain wants to spend the day stumping as usual. But looming over his campaign is the possibility of a statement from one of the women he allegedly harassed sexually back in the 1990s.After spending a day in New York largely shielded from media attention, Cain will step back into public view in Washington for a speech Friday to a group aligned with the tea party movement.The event was on Cain's schedule well before damaging sexual harassment accusations dating from his days as head of the National Restaurant Association became public.Cain says his campaign will get back on message as it tries to move beyond the building sex scandal.
