WATCH: Video shows US clerk refusing to issue same-sex marriage licence
An official in Kentucky who is continuing to deny marriage licences to gay couples said she is doing so "under God's authority".
Rowan County clerk Kim Davis emerged from her office after some couples were denied the licences.
She asked David Moore and David Ermold, who have been rejected four times, to leave. The pair, who were surrounded by reporters and cameras, refused.
Mr Ermold said: "We're not leaving until we have a licence."
Ms Davis responded: "Then you're going to have a long day."
Her supporters whooped from the back of the room, saying "praise the Lord" and "stand your ground".
Others shouted that Ms Davis is a bigot and told her: "Do your job."
The US Supreme Court yesterday declined to intervene in the case, leaving Ms Davis no legal grounds to refuse to grant licences to gay couples.
A district judge could now hold her in contempt, which can carry steep fines or jail time.
She stopped issuing marriage licences in the days after the US Supreme Court's landmark decision to legalise gay marriage across America earlier this summer.
