Franklin Graham, the son of evangelist Billy Graham, has criticized a federal judge's ruling striking down North Carolina's ban on gay marriage.

In speaking with NBC affiliate WCNC, Graham, head of the Billy Graham Evangelist Association, called the ruling “sad.”

“It's sad when a judge is able to overrule the will of the people,” Graham told the station. “This is a democracy, and the people spoke, and we're seeing that activist judges across the country are overturning the will of the people. We saw that in California. We're now seeing it here in North Carolina now. I don't know what will take place.”

U.S. District Court Judge Max. O. Cogburn Jr. declared the ban invalid on Friday after denying GOP legislative leaders the right to intervene in the case.

Graham strongly backed passage of the state's 2012 constitutional amendment which excludes gay couples from marriage.
