Republican presidential candidate Scott Walker suggested in an interview Sunday that the U.S. should protect its border with Canada by building a wall along the entire length.
Walker, the governor of Wisconsin, was asked about how he would address illegal immigration during an appearance on NBC's Meet the Press. The issue is a popular one for Republican presidential candidates lately, although their focus has been on the border with Mexico.
Meet the Press host Chuck Todd asked Walker why the candidates are only talking about the southern border, rather than the possibility that terrorists could cross in the U.S. from Canada, the Associated Press reports.
Walker said his campaign has received questions about a northern wall from some people in New Hampshire.
"They raised some very legitimate concerns, including some law enforcement folks that brought that up to me at one of our town hall meetings about a week and a half ago," Walker said. "So that is a legitimate issue for us to look at."
He added that the idea is just one piece of his broader approach to security issues, the Milwaukee Journal Sentinel notes.
Donald Trump is the most vocal of the Republicans in the presidential race on the immigration issue. He has called for a wall or fence to be built along the entire length of the U.S.-Mexico border - with Mexico paying the tab.
Trump also said he wants to take away automatic citizenship for children of undocumented immigrants who are born in the United States. The "birthright citizenship" is guaranteed by the 14th amendment to the Constitution.
At one point Walker said he supported Trump's position on ending birthright citizenship, but later backtracked and said he's against the idea.
Reaction to Walker's comments was predictably mixed.
