Carly Fiorina continues to make the case for her candidacy, stopping in Oklahoma City to address the Oklahoma Independent Petroleum Association. She told the audience she’d overhaul the Environmental Protection Agency, calling the U.S. a “nation of rules” not laws.

Fiorina cautioned it would take a “global effort to fix global warming” and urged the crowd to “read the fine print.”

“All the scientists who tell us that global warming and climate change is manmade and real, they will also say that with current technology, it will take a concerted effort, coordinated over 30 years, costing trillions of dollars, to make any difference at all,” Fiorina added.
