US-Canada border wall a 'legitimate' proposal, says presidential candidate Scott Walker

The Republican presidential candidate Scott Walker has said that building a wall on the US northern border with Canada was “a legitimate issue for us to look at”.

Asked in an interview on NBC on Sunday if he wanted to build a wall on the Canadian border, the Wisconsin governor cited his experience talking to voters “including some law enforcement folks” in New Hampshire, an early voting state. Such people, he said, were concerned about terrorists potentially crossing over from Canada.

“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.”

In recent months, with the rise in polls concerning the Republican presidential field of businessman Donald Trump, political debate in the US has focused on illegal immigration and the desirabilty and feasibility of building a wall on the southern border, with Mexico.

However, concerns about the border with Canada , a country that has witnessed two attacks by Islamist terrorists in the past year, have so far gone unaddressed.

Immigration and border security remains a live issue in the Republican primary. Another candidate trailing Trump in the polls, New Jersey governor Chris Christie, on Saturday told an audience in New Hampshire he would ask the chief executive of FedEx to devise a system to track illegal immigrants like packages.
