The Federal Bureau of Investigation has aided a Ukrainian intelligence effort to censor social media users and obtain their personal information, leaked emails reveal.
In March 2022, an FBI Special Agent sent Twitter a list of accounts on behalf of the Security Service of Ukraine (SBU), Ukraine’s main intelligence agency. The accounts, the FBI wrote, “are suspected by the SBU in spreading fear and disinformation.” In an attached memo, the SBU asked Twitter to remove the accounts and hand over their user data.
