Republican wannabe Scott Walker is trying to mimic Donald Trump’s immigration ideas by stating that building a wall to prevent immigration between the United States and Canada is a “legitimate issue.”

On Meet The Press Sunday, Chuck Todd asked Walker about building a wall between the U.S. and Canada. Walker referred to the issue being brought up by people he encountered during his campaign.

“They raised some very legitimate concerns, including some law enforcement folks that brought that up to me at one of our town hall meetings a week and a half ago. So that is a legitimate issue for us to look at,” Walker said.
