Choking back tears at a news conference before her return to work, a defiant Davis said she is faced with a "seemingly impossible choice ... my conscience or my freedom," referring to her opposition to same-sex marriages.
"I'm no hero," she added.
Despite her assertion that her deputies don't have her authority to issue marriage licenses, Rowan County Deputy Clerk Brian Mason issued a license this morning to the first same-sex couple to apply after Davis' return to the office. Davis never left her office during the process.
Davis also told reporters this morning that she wants the licenses to indicate that they are being issued under federal authority.
She returned to work today nearly one week after being released from jail for failing to issue marriage licenses over her religious objection to same-sex marriage.
Davis filed an appeal Friday that asks for another delay in issuing the licenses. If the court does not respond before Davis returns to work, she will have to choose whether to allow her office to continue issuing licenses or again disobey the judge who already sent her to jail.
U.S. District Court Judge David Bunning wrote that his mandate to issue licenses applied to all couples, not only those who filed suit. But Davis' lawyers allege that order was issued improperly, and again have asked for a delay.
