Before talking to reporters, Santorum fired 12 rounds at a target at the shooting range. While he was shooting, a woman in the crowd yelled, "Pretend it's Obama."
Santorum, who was 30 yards (meters) away and wearing hearing protectors, said he did not hear the comment.
"That's absurd. I'm not pretending it's anybody. We're shooting pistols. That's a very horrible and terrible remark, and I'm glad I didn't hear it," he said.
The Secret Service said it was investigating the incident.
