Oklahoma Attorney General Scott Pruitt believes a federal judge's order striking down the state's ban on gay marriage will be overturned because there is no constitutional right for gay couples to marry.

“Is there really a constitutional right?” Pruitt, a Republican, rhetorically asked. “[Are] there cases that support that individuals' sexual orientation should be the heart of equal protection under the 14th Amendment? And that's just not the case.”

Pruitt insisted that courts have already rejected the argument.

“When you look at where the Equal Protection Law came from, the 14th Amendment, the right to be treated equally under the laws, it came after the Civil War,” Pruitt said, adding that the amendment was written to protect people from discrimination based on race or gender, not behavior.

In his 68-page ruling, U.S. District Judge Terence Kern said that Oklahoma's 2004 voter-approved constitutional amendment, known as Question 711, violated the 14th Amendment of the U.S. Constitution. A separate ruling striking down Utah's ban also cited the provision.
