A whistleblower group is suing the Department of Justice over its efforts to "secretly surveil" congressional staff conducting oversight on the FBI's Trump-Russia investigation. Empower Oversight Whistleblowers and Research says in a civil suit filed Tuesday that the DOJ has repeatedly stonewalled records requests involving the "undisputed" surveillance. Its suit seeks to force the Justice Department to hand over records related to the alleged unconstitutional surveillance. Empower's founder, Jason Foster, discovered in October that he was one of those congressional staff members surveilled by the Justice Department while serving as Iowa GOP Sen. Chuck Grassley's chief investigative counsel. "Last fall, @Google told me @TheJusticeDept forced it to secretly turn over my comms records in 2017," Foster posted on X, referencing a Sept. 12 subpoena that year for his private cell phone and email communications. Foster confirmed the DOJ and FBI also "targeted a dozen or so other Capitol Hill attorneys' personal accounts " from both political parties" who were looking into the FBI misconduct that included Foreign Intelligence Surveillance Act abuses as well. Both federal law-enforcement agencies later imposed non-disclosure orders for six years on Google and other big tech giants such as Apple and Verizon that had been subpoenaed for congressional staff communications.
