WASHINGTON -- Wisconsin Gov. Scott Walker (R), a staunch advocate of beefing up security on the southern border, said Sunday he is open to building a wall on the U.S. border with Canada as well.
The Republican presidential candidate said the idea of building a northern wall was brought up to him during a recent town hall in New Hampshire.
"That is a legitimate issue for us to look at," Walker said Sunday on NBC's "Meet the Press."
Republicans typically take a tough approach on securing the southern border, but few have said a wall should also be built along the U.S.-Canada border.
Walker reasoned that it's about much more than building a wall, arguing, "It starts with securing the homeland."
"It wasn't just about building a wall and securing our borders," he said. "It was also about making sure our intelligence community has the ability for counterterrorism and the ability to go after the infrastructure they need to protect us."
Talk of constructing a towering wall at the nation's southern border became a hot topic for Republicans after the first GOP debate and consistent mention of it by Republican front-runner Donald Trump.
Trump has said he would build a "big, beautiful wall" on the border to keep undocumented immigrants out.
In fact, there is currently 700 miles of fencing along the southern border already, and apprehensions of those crossing illegally are at some of the lowest numbers they've been in the last decade.
Still, Walker stressed the need to "secure borders in general."
"We spend all this money on TSA. But I think right now one of the most rampant spots is on our southern-based border," he said.
