The National Organization for Marriage (NOM) on Tuesday criticized President Barack Obama for inviting Jim Obergefell to attend his final State of the Union address.

Obergefell served as lead plaintiff in the Supreme Court case that found that gay and lesbian couples have a constitutional right to marry.

He was among the guests seated with First Lady Michelle Obama.

“It’s an outrage that President Obama is honoring the extermination of true marriage in our nation’s laws as a result of an anti-constitutional, illegitimate ruling of the US Supreme Court,” said NOM President Brian Brown. “President Obama is trying to honor something that is completely dishonorable because it strips from the law the truth of marriage as the union of one man and one woman, and substitutes a fiction from the left that marriage can be anything you want it to be.”

NOM called on the Republican leadership to “set aside a vacant seat in front of the chamber in honor of the missing 50 million voters whose votes were stolen by the Supreme Court ruling in the Obergefell v Hodges case.”

“If the President wanted to do justice concerning this ruling, he would have invited all the people of faith who have been victimized by it – bakers, florists, photographers, nonprofit groups, etc. – and apologized to them and the American people for the supreme lie that is same-sex ‘marriage.’ The Obergefell ruling has exposed the falsehood that there would never be consequences for redefining marriage, our most fundamental and important social institution,” he added, referring to the handful of business owners who have faced legal action over their refusals to serve gay and lesbian couples.
