Wisconsin Gov. Scott Walker joined Bret Baier on "Special Report" to discuss Hillary Clinton and some of the key issues on the campaign trail, including immigration.

The 2016 presidential candidate asserted that Bill and Hillary Clinton believe they follow a different set of rules than everyone else.

"Basic ethics 101 would tell you it's a conflict of interest to take money, to have your spouse take money, from foreign countries at the same time someone is Secretary of State," Walker said. "This is just part of a pattern that I think many Americans, not just Republicans, are concerned with, many Americans are frustrated with."

Walker also weighed in on the immigration debate, calling for the U.S. to secure the border, enforce the law and not grant amnesty to illegal immigrants.

"We're a nation of immigrants. I love the people who have come here from other places around the world. They want to live the American Dream. That's great," Walker said. "But we have a broken system today that needs to be fixed."

"For legal immigration, we need to have a system that makes sure that American workers and wages are at the top of our list of priorities."
