He was at the center of a Supreme Court case that changed gay marriage. Now, he's worried.

When Jim Obergefell was sitting in the gallery at the Supreme Court on June 26, 2015, he was waiting to hear his name. The justices were preparing to rule on Obergefell v. Hodges, a case that became a landmark in the progress toward LGBTQ+ rights in the U.S. The case, which considered the rights of same-sex couples to marry, ultimately won favor with a majority of the justices, but for Obergefell, the moment wasn’t, and could never be, totally complete.

His husband, John Arthur, died years before the ruling was announced.

Now, 10 years on, he sat down with USA TODAY to reflect on how their love for each other helped shape the fight for marriage equality in the U.S., and what progress there is to still be made in the fight for equality.

Obergefell and Arthur met in 1992 and became engaged in 1993. That’s when their journey as marriage equality pioneers first began – and for Obergefell, continues into the present.
