"We're all under attack by this administration."
Jim Obergefell took his fight for marriage equality all the way to the Supreme Court in 2015 and won.
But today despite that landmark ruling he is worried that it could be reversed.
TMZ caught up with the activist and author at LAX and he expressed his concerns that the Constitutional right to marry the person of your choice might one day be overturned.
"I definitely am worried what with the changes to the Supreme Court and with this administration who will -- who has continued to nominate conservative judges across the country," he said.
"The federal judiciary has changed dramatically and all it takes is the right case to get in front of the right judges for that to end up in front of the Supreme Court again. And if that happens right now I just Have to rely on Chief Justice Roberts being a stronger believer in precedence than he is in overturning something he didn't agree with in the first place."
Obergefell's fear stems from recent additions to the U.S. Supreme Court bench. Trump's picks; Neil Gorsuch and Brett Kavanaugh swing the balance of the court to the right.
It's significant because the gay marriage decision was decided by a 5-4 vote.
