In the past, I have been an immigration reformer, not a restrictionist.

In the 1980s and 1990s, radical change in economic policies fostered by Ronald Reagan and Margaret Thatcher put the brakes on government planning and ushered in a new free-market supply-side era and a two-decade boom. That model has been abandoned in the new century. This must be reversed.

Obamacare rules and mandates are job-killers.

It turns out that Donald Trump has been very good at buying low and selling high, and it helps account for his amazing business success.

My efforts in Congress are guided by the belief that environmental preservation and restoration are a critical part of the legacy we leave to future generations.

Climate change is analogous to Lincoln and slavery or Churchill and Nazism: it's not the kind of thing where you can compromise.

Despite Arizona's remarkable growth in recent years, we have met the current federal health standards for ozone pollution and the Environmental Protection Agency recently approved our dust control plan.

My view is that climate changes have happened in the last 80 years, that is, the world has got a little bit warmer, although not as warm as it has been in Medieval times, or the Bronze Age.
