She said sources inside the Department of Justice confirmed Facebook spied on those who expressed anti-government or anti-authority sentiments, or questioned the 2020 election, and reported their statements to the FBI.
“Under the FBI collaboration operation, somebody at Facebook red-flagged these supposedly subversive private messages over the past 19 months and transmitted them in redacted form to the domestic terrorism operational unit at FBI headquarters in Washington, DC, without a subpoena,” she said.
One of the sources told her, “It was done outside the legal process and without probable cause. Facebook provides the FBI with private conversations which are protected by the First Amendment without any subpoena.”
Devine's report explained those messages then were used as “leads,” given to FBI agents around the country who then sought subpoenas to officially access the conversations.
