But it's Republicans, so far mostly silent, who will decide Greene's fate in the House.
On Friday, Greene remained resolute in the face of increasing criticism and even offered a warning to her fellow conservatives.
"I will never back down. I will never give up. Because I am one of you. And I will always represent you," she said in a statement posted to her nearly 300,000 Twitter followers. "If Republicans cower to the mob, and let Democrats and the Fake News media take me out, they're opening the door to come after every single Republican until there's none left."
