The state's gathering of conservative activists, scheduled for this weekend in Harrisburg, now almost has a full presidential slate on its agenda.
He's now joined on the schedule by South Carolina Gov. Nikki Haley, who will speak Friday afternoon on Mitt Romney's behalf.
Newt Gingrich (who has roots in Harrisburg and Lebanon County) also will appear. He is scheduled to close out Saturday panels, which include a debate of U.S. Senate candidates, around 1:30 p.m.
