Biden said culture and arts changed people's attitudes. He cited social media and the old NBC TV series "Will and Grace" as examples of what helped changed attitudes on gay marriage.
Biden said, "Think – behind of all that, I bet you 85% of those changes, whether it's in Hollywood or social media, are a consequence of Jewish leaders in the industry."
Biden said the influence was immense and that those changes had been for the good.
Biden spoke Tuesday night at a Jewish American Heritage Month reception hosted by the Democratic National Committee. He said Jewish values were an essential part of who Americans are.
