TULSA, Oklahoma - The United States Supreme Court made a landmark ruling Friday, allowing gay couples in every state the right to marry.

While supporters of same-sex marriage spent the day celebrating, some activists and politicians are already challenging the court's 5-4 decision.

Gay rights activists celebrated across the country after the Supreme Court ruled same-sex marriage bans unconstitutional, but supporters said the fight for equal rights still isn't over.

In Tulsa, those who challenged Oklahoma's same-sex marriage ban were happy about Friday's 5-4 decision.

A federal judge ruled earlier this year Oklahoma's ban on same-sex marriage was unconstitutional, saying the ban violated the 14th Amendment.

Oklahomans for Equality Advocacy Chairman Mike Redman said same-sex couples already married in Oklahoma can now be recognized across the country.

"When we leave the state and go to Texas our marriage doesn't end at the border. Now when we go to Texas, Texas is obligated to recognize lawful marriages performed in Oklahoma," Redman said.

Neither of Oklahoma's two senators was happy with the high court's decision.

"It's a very liberal court and we saw what happened last week. I've been disappointed, and I was not surprised, I thought they would rule the way they did. I know a lot of people, actually a lot of people who are friends of mine in the gay community, who also think it was a bad decision," Senator Jim Inhofe said.

He said recent Supreme Court decisions are reflecting political positions on issues instead of strictly interpreting the law.

"We have expanded the role of judicial activisms in the courts. It's been…look at ObamaCare. I appreciate Scalia standing up and talking about some of these things as a minority," Inhofe said.

Redman said he's glad to know his relationship is now recognized by law and he's entitled to equal rights.

"This is a huge hurdle, it is a landmark, historical day, but it's not the end of the race," he said.

Redman said part of the fight for equality includes health and benefit plans for domestic partners and equal housing protections for the LGBT community.
