Rep. Michele Bachmann (R-MN) received another uncomfortable moment on the campaign trail about her anti-gay views Sunday evening.

According to CNN, the congresswoman and her husband Marcus encountered Kathy Schnell, a woman wearing a Bachmann sticker and holding up a sign saying "Gay-friendly Iowan."

While smiling to sign the poster, Bachmann asked "Gay-friendly Iowan?"

Schnell proceeded to pick Bachmann's brain on the number of America gays.

"I wonder if you're aware that 10% of the population is gay?" she said. "And if you have 28 children, then 2.8 of those kids are very likely gay."

Thinking that the GOP presidential candidate wasn't listening to her, Schnell told her friend "She's not listening to me."

That prompted Bachmann to reply, "Well, that's according to the Kinsey Report."

A few seconds later, her husband Marcus jumped in and told Schnell, "Your facts are wrong."

"That's not valid?" Schnell replied back.

"No it isn't," he said. "No, it's not at all. It's been a myth for many years."

The Kinsey reports are based on the two books written by Dr. Alfred Kinsey about human sexual behavior in 1948 and 1953. It is widely considered groundbreaking research that helped change popular perceptions about the size and make-up of America's LGBT population.

This isn't the first time Bachmann has been confronted on the campaign trail about her views on LGBT rights and the community at large."

Two weeks ago, Bachmann encountered a 8-year-old who told her, "My mommy’s gay but she doesn’t need any fixing."
