APPLETON - Former President Bill Clinton, making a campaign stop here on behalf of his wife, Democratic presidential candidate Hillary Clinton, took a swipe at GOP front-runner Donald Trump for wanting to build a wall on the country’s southern border.

“Building a wall is a bad idea,” he told a crowd of 650 Friday morning at Lawrence University in downtown Appleton.

“We can do this," he said in reference to creating a stronger middle class, "but we can’t do this until we tear down (economic) barriers.”
