A prominent tea party-backed Republican lawmaker is spearheading a bipartisan proposal that would protect religious institutions and other nonprofit groups that don't recognize same-sex marriages from potential discrimination by the Internal Revenue Service. The bill drafted by Rep. Raul Labrador (R-Idaho) is a "narrowly-tailored piece of legislation" that would protect groups "from discrimination by the federal government," he said in an interview this week. Labrador said he began drafting his proposal partly out of fear that the IRS and other federal agencies might unfairly target groups that oppose same-sex marriage after the Supreme Court struck down a federal law barring same-sex couples from obtaining federal benefit this summer.
