House Oversight Committee Chairman Darrell Issa said Sunday that he believes there were more Secret Service agents involved than current figures say in the prostitution scandal that broke Friday night.
"We think the number might be higher. And we're asking for the exact amount of all the people who 'were involved,'" Issa said on CBS' Face The Nation. An upcoming investigation, he said, will be "about how did this happen and how often has this happened before. Things like this don't happen once if they haven't happened before."
