At a campaign event in Iowa, New Jersey Gov. Chris Christie took on President Obama on a number of foreign policy related issues and criticized him for his focus on climate change in a speech to the United Nations last week.

“He spends more time on climate change than he spends on the global terrorist threat to America and the other free nations of the world,” Christie said.

Christie believes human activity is a cause of climate change, but disagrees with the regulatory approach supported by the Obama Administration.
