Mat Staver, the lead attorney for Kim Davis, told Bill O'Reilly tonight that Davis returned to work, but she has had to deal with an intense backlash, including death threats.

Davis, the Kentucky county clerk at the center of a national firestorm over her refusal to issue same-sex marriage licenses, had to change her home phone number, according to Staver.

"She's gotten death threats that people are going to come to the office, kill her and kill all of her staff," Staver said. "We've gotten death threats for the same thing, that we're going to be carried out in body bags. We've gotten death threats that we're going to have bullets in our heads."

"That kind of rhetoric I don't think is going away quickly, but the intensity of it surprised all of us."
