The accusations of her being a part of the Church of Satan came flooding in on Twitter after she wished the group a Happy New Year.
Far-right activist Jack Posobiec shared a photo of the conversation.

Many Twitter users viewed the greeting as an endorsement of the organisation or an inclination that she was a part of it.
They include Twitter user Rhonda Kazmierski who said in a tweet which since been deleted: "At least @ChelseaClinton is open about worshiping #Satan. #ChurchOfSatan If only @HillaryClinton could be as honest."
Replying to the tweet, Clinton denied the accusation, and said she's a Methodist.
Oh goodness gracious. We can be civil, cheerful, respectful to & friends with people who don't share our religious beliefs. Sometimes, we even marry them. I'm a Methodist & my husband is Jewish, thank you for asking. A very happy New Year to you Rhonda! https://t.co/8UH9SP8EWO— Chelsea Clinton (@ChelseaClinton) January 3, 2018
The Church of Satan has responded to the controversy, supporting Clinton and reminding people that the group doesn't worship Satan despite what its name may indicate.
And neither do we. Like we stated before, if someone is polite to us, we respond in kind. We've been very courteous with folks on the other side of the political spectrum who approached us the same. That this is shocking news is fascinating in and of itself. https://t.co/whcTZQ9kdz— The Church Of Satan (@ChurchofSatan) January 3, 2018
In February 2016, the daughter of Bill and Hilary Clinton revealed in an interview with Life News that she left the Baptist church to become a Methodist because she believes in abortion rights.
