First Lady Michelle Obama said in a video released Thursday that supporting gay marriage is about the “basic values” of fairness and equality she taught her daughters.

“In a country where we teach our children that everyone is equal under the law, discrimination against same-sex couples just isn't right,” Obama said. “It's as simple as that.”

In the video, the first lady answered four questions from Twitter followers, including one from @Flower4444, who asked, “Please tell us about your family discussions about marriage equality and thank President Obama for his support!”

“This is an important issue for millions of Americans,” Obama answered. “And for Barack and me, it really comes down to the values of fairness and equality that we want to pass on to our girls. I mean these are basic values that kids learn at a very young age and that we encourage them to apply in all areas of their lives.”

“Thank you so much for this question. And we're proud to have your support,” she added.

The video ends with footage of a gay and a lesbian couple. The male couple is seen reading to their toddler daughters. (The video is embedded in the right panel of this page. Visit our video library for more videos.)
