In the book, Andy helps his uncle Mike plan his wedding to Steve.
Leno's support for the book at its March 5 launch party in San Francisco didn't sit well with NOM, the nation's most vociferous opponent of gay marriage.
In a blog post titled After Gay Marriage: What Next? CA Senator honors children's book on SSM, the group took at a swipe at Leno.
“CA State Senator Mark Leno has issued a proclamation to coincide with the launch of My Uncle's Wedding, a new book which introduces children as early as 4 to same-sex marriage,” the group wrote.
Leno congratulated the book's author, Eric Ross, and said My Uncle's Wedding “serves as a conduit by which to bolster understanding in our community.”
Comments on the NOM blog ran mostly negative.
