WATCH: President Obama's Full Interview About Gay Marriage

President says daughters influenced his decision to support gay unions.

President Barack Obama's historic announcement of support for legalization of gay marriage has given activists, political pundits and voters something new to mull over this weekend.

In his Thursday morning interview with ABC's Robin Roberts, Obama also revealed that daughter Malia and Sasha influenced his decision on the controversial topic.

From Obama's Good Morning America interview:

And we've been talkin' and — about their friends and their parents. And Malia and Sasha would — it wouldn't dawn on them that somehow their friends' parents would be treated differently. It doesn't make sense to them. And — and frankly — that's the kind of thing that prompts — a change of perspective. You know, not wanting to somehow explain to your child why somebody should be treated — differently, when it comes to — the eyes of the law.
