Donald Trump’s Mar-a-Lago resort appears to employ a pastry chef who frequently posts online about her belief in the pro-Trump QAnon conspiracy theory.

Elizabeth Alfieri, a Florida pastry chef, has posted dozens of times on Instagram using QAnon hashtags and slogans, often using pictures taken at Mar-a-Lago itself. Alfieri’s Instagram posts were first reported by 1100 Pennsylvania, a newsletter that reports on Trump’s properties.

On Christmas, for example, Alfieri posted an Instagram picture of a gingerbread house in what appears to be a Mar-a-Lago ballroom. The side of the gingerbread house is emblazoned with a “Q” made of blue frosting and dusted with glitter.

It wasn’t clear whether Alfieri herself had added the frosted “Q.”

“Merry Christmas from the Jewel of Palm Beach,” Alfieri wrote, adding a “#QAnon” hashtag and the acronym “WWG1WGA,” a reference to the QAnon slogan “Where we go one, we go all.”

QAnon centers on thousands of clues posted by an anonymous person called “Q,” who posits a world of Satanic rituals reminiscent of the Pizzagate conspiracy theory. QAnon believers think that Trump is engaged in a shadowy secret war against pedophiles in the Democratic Party and Hollywood.

QAnon believers have been involved in dangerous incidents, with one charged with shutting down a bridge near the Hoover Dam with an improvised armored truck and another accused of murdering his brother with a sword because he thought he was a lizard.

Alfieri and the Trump Organization didn’t respond to requests for comment. Alfieri’s LinkedIn page shows her in a chef’s uniform with the Mar-a-Lago logo on it, and she’s described on the menu for a charity fundraiser as a chef at Mar-a-Lago.

Alfieri made her Instagram private after being contacted by 1100 Pennsylvania, although some of her posts are preserved online through aggregator sites and in screenshots.

In her profile on a pro-Trump group’s website, Alfieri writes that she quit her last job to “have the privilege of using my talents for the service of the First Family.” Since then, Alfieri appears to have gained access to Mar-a-Lago’s inner-workings.

On New Year’s Eve, she posted an Instagram picture of a fishing-themed birthday cake intended for Donald Trump Jr. when it was still in the kitchen, adding a QAnon-related hashtag to the post. A Google Reverse Image search doesn’t turn up any other examples of the picture online that weren’t related to Alfieri’s Instagram.

Trump Jr. later posted a picture of himself with the same cake on Instagram.

Alfieri also claimed to interact with the Secret Service at Mar-a-Lago. She posted pictures of Secret Service security pins, tagging them with QAnon-related hashtags.

Those aren’t the only QAnon references on Alfieri’s Instagram. She once posted a picture of a Mar-a-Lago table marked “17,” a number that is important to QAnon believers because “Q” is the 17th letter of the alphabet.

“Merry Christmas Anons everywhere! #wwg1wga #Qanon #Q,” Alfieri wrote, alluding to QAnon believers who call themselves “Anons.”

Alfieri has found ways to tie her passion for baking into QAnon. In January, she posted a picture of a bundt cake with a slice cut out to form a “Q.”

“Nothing to see here,” Alfieri wrote in the caption, adding the hashtag #doyouseemeQ.

Alfieri has also made QAnon references on her Twitter account, which has been deleted. She uses QAnon slogans in her Twitter bio. She also interacted on Twitter with “@TheRealRAnon,” a Twitter account that pretends to be John F. Kennedy Jr., who QAnon believers claim is still alive.

This isn’t the first time a QAnon believer has been close to a top Trump administration official. Trump met in the Oval Office with QAnon promoter Lionel Lebron in August. A Florida SWAT Team officer wore a QAnon patch while protecting Mike Pence in November, and was ultimately demoted for wearing the patch.
