I don't know the science behind climate change. I can't say one way or another what is the direct impact, whether it's man-made or not. I've heard arguments from both sides, but I do believe in protecting our environment, but without the job killing regulations that are coming out of the Environmental Protection Agency.

It will take hard work, but doing nothing on Social Security, for example, simply makes sure the system will go broke. It's time to make some reforms.

I grew up castrating hogs on an Iowa farm, so when I come to Washington, I'll know how to cut pork.

Healthcare should be about market driven solutions, not government mandates.

When we do go to combat, it should be with a defined mission and a plan for withdrawal.

Over the longer term, we need to work toward a pro-growth tax code that is fairer and simpler than what we have now. Anything that meets those criteria is going to be better than the failing and dysfunctional tax code we have today.

We need to repeal and replace Obamacare. It is the largest tax in U.S. history, has proven to be a job-killer, and has driven up the cost of healthcare.
