Special Counsel Robert Mueller’s team alerted Judge Amy Berman Jackson on Monday that Roger Stone posted an image on Instagram that might have violated his gag order over the weekend.

The post in question was a picture of Stone under the words: “Who framed Roger Stone?” It also linked to a page for donors to contribute to the fund for Stone’s legal defense.

Stone is currently facing charges for lying to Congress and obstructing justice as a part of Mueller’s Russia investigation. After he posted a photo of Judge Jackson next to an image of crosshairs with a conspiratorial caption about the case against him, she issued a gag order against him, barring him from speaking publicly about his case, citing concerns about public safety.

There’s a key exception to Stone’s gag order: He is still allowed to proclaim his innocence. However, the new post itself, which directly implies that he’s being framed, seems to go above and beyond a mere proclamation of innocence.

Mueller did not take a position in the filing on whether the post did, in fact, violate the order.

The filing from Mueller’s team came in response to Stone’s request for clarification about the gag order. Stone’s lawyers wanted to know whether the order covers a reprinting of a book by Stone, which will include a new introduction written before the gag order was issued.

According to BuzzFeed News, Stone calls Mueller “crooked” in the new book introduction.
