X removes access to the compromised JD Vance dossier links.

X is blocking users from sharing links to a newsletter featuring a document allegedly hacked from the Trump campaign that contains research on vice presidential candidate JD Vance. The journalist behind the newsletter, Ken Klippenstein, has been suspended from the platform. Searches for posts with the newsletter's link yield no results.

The document is said to have originated from an Iranian hack of the Trump campaign, and while other news outlets have received details from the breach, they chose not to publish. Klippenstein claims that a source named "Robert," who has an AOL email address, provided him with the document, which reportedly includes Vance’s full name, addresses, and parts of his social security number.

KlipNews, the X account for the newsletter, stated, "Ken Klippenstein has been banned by Twitter for publishing private information in contradiction of its rules." Before Elon Musk's acquisition, Twitter had a policy against posting hacked materials, which is no longer available online. A version of this policy from 2019 stated that sharing or linking to hacked content was prohibited, exemplified by the banning of a New York Post story about Hunter Biden. However, in October 2020, Twitter revised its stance, deciding not to block hacked materials after criticism of how it handled the Post article. Former CEO Jack Dorsey acknowledged the error of outright blocking URLs.

Musk himself criticized the decision to ban links to the Post’s story, describing it as "incredibly inappropriate" to suspend a major news organization for reporting factual information. He even invited former Rolling Stone columnist Matt Taibbi to review internal documents related to Twitter's decision-making process, during which Taibbi inadvertently revealed the email addresses of Dorsey and Representative Ro Khanna.

The reason behind X's decision to block Klippenstein's story remains unclear. Attempts by three staff members at The Verge to share links to the newsletter were unsuccessful, receiving error messages that stated, "We can’t complete this request because this link has been identified by X or our partners as being potentially harmful.
