Carly Fiorina said on Tuesday that she doesn't "think walls are particularly effective," arguing that America should instead use "technology" to secure its northern and southern borders.
Asked by radio host Michael Medved about rival GOP presidential candidate Scott Walker's comments that a wall separating the U.S. and Canada was a "legitimate issue for us to look at," Fiorina said "if that's what it took," she would do it, but that she was skeptical of walls in general.
"I don't think walls are particularly effective," she said. "I mean, if that's what it took to do it, I would do it, North or South. But I think technology has advanced to the point where it is far quicker, far less expensive, and actually far more effective to deploy technology."
Fiorina became the latest Republican presidential candidate to comment on Walker's remark about a northern wall since he made it on Sunday. Rand Paul said on Monday that he thought such a wall was "a pretty dumb idea." Mike Huckabee said the same day that he was "not aware" of a "major problem of people coming across the Northern border," but that, "if we did have that problem, then we would need to secure that border as well."
Walker has since argued that his comment was widely misinterpreted.
Later in the interview, Fiorina added that "we've invested a lot of money" in the northern border since 9/11, but that "spending the money doesn't seem to translate into any results."
"And yes, I do think we need to be focused on our northern border as well," she said. "Although I will tell you, having been up around that border a lot, that we've invested a lot of money in that border since 9/11 and it's one of the mysteries of the ineffective bureaucracy that the federal government has become that sometimes—too often, frankly—spending the money doesn't seem to translate into any results which is part of the set of problems we've got to solve."
