Chelsea Manning, who is currently serving a 35-year prison sentence for leaking government documents to WikiLeaks, has been threatened with possible “indefinite solitary confinement” for a series of seemingly trivial infractions, including owning expired toothpaste and “sweeping food onto the floor,” her lawyer said on Wednesday.

ACLU attorney Chase Strangio says Manning is additionally accused of “disrespect” for requesting her lawyer while speaking to a guard and “prohibited property” for owning books and magazines that include the Caitlyn Jenner cover issue of Vanity Fair.

In response to the charges, Manning’s supporters have started an online petition providing a detailed list of her alleged violations:

According to the website, Manning’s “prohibited property” was as follows:

Vanity Fair issue with Caitlyn Jenner on the cover, Advocate, OUT Magazine, Cosmopolitan issue with an interview of Chelsea, Transgender Studies Quarterly, novel about trans issues “A Safe Girl to Love,” book “Hacker, Hoaxer, Whistleblower, Spy — The Many Faces of Anonymous,” book “I Am Malala,” 5 books by Robert Dorkin, legal documents including the Senate Torture Report, book: “Hidden Qualities that Make Us Influential.”

“Given the materials that were confiscated, it is concerning that the military and Leavenworth might be taking action for the purpose of chilling Chelsea’s speech or even with the goal of silencing her altogether by placing her in solitary,” Strangio told Buzzfeed News. “Hopefully with public scrutiny the prison will respond by dismissing these charges and ensuring that she is not unfairly targeted based on her activism, her identity, and her pending lawsuit.”

Manning’s attorney says she is scheduled to have a hearing on the charges on August 18th.

The Associated Press reports that military officials have yet respond to requests for comment.
