A county clerk in Kentucky who has repeatedly defied court orders by refusing to issue marriage licenses will appear before a federal judge who could hold her in contempt of court.

Rowan County clerk Kim Davis has been summoned to the hearing at 11 a.m. Thursday before U.S. District Judge David Bunning. He's also ordered all Davis' deputy clerks to appear. Bunning could hold Davis in contempt, which can carry hefty fines or jail time.

Davis stopped issuing licenses to all couples in June after the U.S. Supreme Court legalized gay marriage. Despite rulings against her, she's turned away couples again and again, citing her Christian beliefs and "God's authority."

The couples who originally sued in the case have asked Bunning to punish Davis with fines but not jail time.
