On that score, he admitted his "You lie" shout at President Obama during his recent congressional address was inappropriate.

"It was brought up possibly the wrong way," Wilson said, drawing laughter from the crowd. Wilson was introduced by Congressman Roy Blunt, the U.S. Senate candidate.

"But the issue has been brought up," he said. "We need to watch them like a hawk."
