“I believe that if you want to be president of the United States, your run for president. You don’t run for president with some eject button in the cockpit that allows you to go on an exit ramp if it doesn't work out.”
Rubio said he believes he’s ready to be president, but he won’t make a decision until the end of this year.
Asked if he’s given up on immigration reform, Rubio said no: “I remain convinced we need to do something serious about our immigration problem in this country.”
The responsibility falls to both Democrats and Republicans, he said: “We’re not going to grant blanket amnesty to 12 million people. We're also not going to round up and deport 12 million people. So that issue has to be dealt with in a reasonable but responsible way.”
Rubio also said he doesn’t agree with the liberal mantra that human activity is causing climate change.
“I don't agree with the notion that some are putting out there, including scientists, that somehow there are actions we can take today that would actually have an impact on what's happening in our climate,” Rubio said. “Our climate is always changing. And what they have chosen to do is take a handful of decades of research and say that this is now evidence of a longer-term trend that's directly and almost solely attributable to man-made activities."
Rubio said he doesn’t know of any era in world history where the climate has been stable. “Climate is always evolving, and natural disasters have always existed.”
“So let me get this straight,” ABC’s Jonathan Karl told Rubio: “You do not think that human activity, the production of C02 has caused warming to our planet?”
“I do not believe that human activity is causing these dramatic changes to our climate the way these scientists are portraying it...and I do not believe that the laws that they propose we pass will do anything about it, except it will destroy our economy.”
The Democratic National Committee issued a statement Sunday following Rubio’s interview, saying, “It’s clear that Rubio would rather throw red meat to the Tea Party base than objectively look at the science of climate change and support common-sense solutions that will help protect the environment and grow our economy.”
