(Fox News) The state of Oregon has launched a discrimination investigation against a family bakery owned by Christians who refused to bake a wedding cake for a lesbian couple.

The Bureau of Labor and Industries will investigate whether Sweet Cakes by Melissa violated a 2007 law that protects the rights of gays, lesbians, bisexual and transgender people in employment, housing and public accommodations.

Aaron and Melissa Klein told Fox News they turned down requests to bake cakes for gay weddings because it goes against the Christian faith and their right to religious freedom.
