"I'm proud to say there's a 99.9 percent chance -- did you get that, 9-9-9?-- that Herman Cain will be here," party Chairman Tom Del Beccaro told reporters at a press conference opening the three-day convention, referring to the former candidate's 9-9-9 tax proposal.
Cain, who dropped out of the race in December amid allegations of sexual harassment, is expected to appear alongside presidential hopeful Newt Gingrich at the Hyatt Regency in Burlingame on Saturday. The former House Speaker is the keynote speaker at Saturday's lunch banquet.
Del Beccaro said conservative radio host and commentator Michael Reagan is also expected to join.
Former presidential hopeful Tim Pawlenty, the former Minnesota governor, is scheduled to address convention attendees during the Saturday dinner program.
