Wolf Blitzer put his foot in his mouth for a moment on Tuesday while interviewing a survivor of the devastating tornado in Moore, Okla.

"We're happy you're here. You guys did a great job," Blitzer said to Rebecca Vitsmun, who escaped from her house with her 19-month-old son right before the twister tore through it. "You've gotta thank the Lord, right? Do you thank the Lord for that split-second decision?"

Vitsmun hesitates for a moment and smiles. "I -- I'm actually an atheist," she said, laughing off the awkward moment.

"You are. All right. But you made the right call," Blitzer said.

"We are here, and I don't blame anyone for thanking the Lord," Vitsmun said.

Though she handled the situation graciously, Blitzer would be well-advised not to assume that every interview subject believes in God. After all, America experienced a 13 percent drop in religiosity between 2005 and 2012, according to a WIN-Gallup poll published last year.
