Christian conservative Mat Staver has predicted that a Supreme Court filled with President-elect Donald Trump appointees will overturn last year's marriage equality ruling.

In Obergefell v. Hodges, the high court found that gay and lesbian couples have a constitutional right to marry.

On Sunday, Trump told 60 Minutes' Leslie Stahl that he was “fine” with the ruling. Conservatives lashed out at Trump, arguing that the court's decision had not settled the issue.

Staver, who heads Liberty Counsel, an anti-LGBT legal advocacy group, responded to Trump's comments during an appearance on WorldNetDaily's Radio America, where he pointed out that Trump has pledged to appoint socially conservative judges to the Supreme Court.

“Just give the opportunity to fill those seats with someone who respects the constitution and this razor-thin 5-4 decision on same-sex marriage, I think, will be in the same trash bin of history that Dred Scott found itself to be in when people began to wake up and have some common sense,” Staver said.
