Scott Pruitt in Trump Cabinet members actions and issues

On Abortion: Double headline - Already Done

Throughout the programs, Pruitt suggested that states might need to call a constitutional convention to propose amendments that would allow expression of religion in government, declare abortion illegal and bar same-sex marriage.

Pruitt acknowledged some trepidation about holding a constitutional convention, which could make wholesale changes to the nation's founding charter.

"It scares me to a large degree to go into something like a constitutional convention, 'cause that means that we're going to have to really be educated, and informed, and debate," he said. "But you know what? Maybe it's time."

On Education: Evolution is unproven theory

"There aren't sufficient scientific facts to establish the theory of evolution, and it deals with the origins of man, which is more from a philosophical standpoint than a scientific standpoint," he said in one part of the series, in which Pruitt and the program's hosts discussed issues related to the Constitution.

Two years earlier, Pruitt had supported an unsuccessful bill that would have required textbooks in Oklahoma to carry a disclaimer that evolution is a theory.

EPA would not say this week whether any of Pruitt's positions have changed since 2005. An EPA spokesman said "if you're insinuating that a Christian should not serve in capacity as EPA administrator, that is offensive and a question that does not warrant any further attention."
