Same sex marriage bill hits a speed bump

(KYMA, KECY/CNN) - In developing news this morning, a bill to protect same-sex marriage nationwide is hitting a speed bump.

Right now, those unions are legal due to a 20-15 supreme court ruling.

After the federal right to abortion was overturned -- Democrats say they want marriage equality on the books.

The bill to codify same-sex marriage in federal law has passed the house.

But it's unclear if enough republican senators would support it -- to overcome a filibuster.

Four republican senators tell CNN they'd vote for the bill.

Eight say they'd oppose it - and sixteen say they're undecided or didn't indicate support.

The rest didn't respond by the deadline.

But lawmakers from both parties say they think the bill will get enough republican votes.

Some republicans feel the right to marriage equality is already settled.

Right now, a supreme court ruling is what's protecting it nationwide.

It uses the same legal principle that had protected abortion access on the federal level.

Justice Clarence Thomas said in his opinion overturning roe -- that he opposes that principle.
