Brian Brown, president of the National Organization for Marriage (NOM), continues to call on President-elect Donald Trump to reverse marriage equality.

Trump has made conflicting statements about last year's Supreme Court finding that gay and lesbian couples have a constitutional right to marry. In 2012, he said that he's opposed to such unions but later confided that he had attended a “beautiful” same-sex wedding. The following year, he said he was “evolving” on the issue. But during the campaign, Trump said that he would sign the First Amendment Defense Act (FADA), a GOP bill that would undermine the marriages of gay couples, and would appoint conservative judges to the Supreme Court in a similar vein to the late Justice Antonin Scalia, a vocal opponent of LGBT rights and a dissenter on the high court's Obergefell ruling.

In an interview with 60 Minutes, Trump said that he was “fine” with the Supreme Court's ruling, though he refused to answer whether he supports marriage equality, saying that his opinion was “irrelevant.”

“It's done. These cases have gone to the Supreme Court. They've been settled. And I'm fine with that,” Trump told Lesley Stahl.

In a tweet the following day, Brown criticized the president-elect.

“Same-sex 'marriage' is #notsettled @realDonaldTrump,” Brown said. “SCOTUS betrayed the constitution. Please stand up for the voters!”

In a blog post on Friday, Brown called on supporters to “help NOM make America great again” by reversing the gains made by the LGBT community.

“NOM can play a powerful role in helping make America great again by mobilizing our supporters, expanding our coalition and serving as a voice for the truth of traditional moral values,” Brown said. “You see, to a very large degree, making American great again means making American families strong again. It means promoting the truth of marriage. It means helping ensure that children receive the love of their mother and father. It means that the truth of gender be respected, and promoted, not ignored and redefined. It means that religious liberty and the faith-principles that undergird our constitution be restored.”

During the GOP primary, NOM backed Texas Senator Ted Cruz for the presidential nomination, saying that Trump had abandoned the fight against marriage equality. In an ad that ran in South Carolina, the group urged GOP voters to “dump Trump” over the issue.
