Obamacare is the nation's biggest job killer and stands in the way of our country's economic growth and prosperity. It should be defunded and repealed. President Obama should hear the pleas from the untold number of Americans who are losing their jobs, wages, and healthcare plans, and Congress should act immediately to stop Obamacare from inflicting any more damage on the country on our hard-working citizens.

America has receded from the world. Today our friends and allies don't trust us. And our enemies don't fear us. I think we should get back, number one, to American leadership in the world.

One of the most troubling aspects of the Rubio-Schumer Gang of Eight Bill was that it gave President [Barack] Obama blanket authority to admit refugees, including Syrian refugees without mandating any background checks whatsoever. Now we've seen what happened in San Bernardino. When you are letting people in, when the FBI can't vet them, it puts American citizens at risk.
