From #CNN:

"While the bill would not set a national requirement that all states must legalize same-sex marriage, it would require individual states to recognize another state’s legal marriage.

"So, in the event the Supreme Court might overturn its 2015 Obergefell v. Hodges decision that legalized same-sex marriage, a state could still pass a law to ban same-sex marriage, but that state would be required to recognize a same-sex marriage from another state."
