Leaving the frozen event, Santorum also declined to take a shot at Romney over a remark earlier from the front-runner that he “likes to fire” workers who are not doing a good job.

“We try to hire good people, we try to keep them employed. If someone if obviously not performing their duty and their mission, obviously a business has a responsibility for the greater good of the business and the other employees to make sure that everybody there is pulling their weight,” Santorum said.

Asked whether Romney’s corporate takeover experience at Bain Capital would be a liability, Santorum said: “I’m not making it a liability. I believe in the private sector.”
