If you're an Islamic terrorist, probably the last program I'd use to try to get into this country is the refugee program.

I'm going to be voting for Donald Trump. I'm going to do everything I can to make sure he wins.

In Wisconsin, we have got a lot of agricultural products that are exported. We have a lot of manufacturing products that are exported. I don't want to engage in a trade war.

Mankind has actually flourished in warmer temperatures.

It doesn't make any sense to continue to elect people like Ron Kind or Russ Feingold, individuals that literally are dedicated to growing the federal government.

Donald Trump's a change agent. So am I.

You don't get further outside than I do going into Washington, D.C.
