The FBI has restricted all the evidence obtained through the wiretapping of former Trump campaign staffer Carter Page.

Revealed in a Jan. 7 filing by the Foreign Intelligence Surveillance Court that was made public on Thursday, the government said the bureau chose to “sequester all collection the FBI acquired pursuant to the Court’s authorizations” to grant a warrant and three extensions for the electronic surveillance of Page, a U.S. citizen who was suspected of acting as an agent of Russia but was never charged with any wrongdoing.

The filing, signed off by presiding FISA court Judge James Boasberg, further stated that the "sequester" would remain in place until the completion of a further review of the DOJ inspector general report on the Page FISA warrants and the "outcome of related investigations and any litigation."

"The government has not described what steps are involved in such sequestration or when it will be completed," Boasberg wrote. "It has, however, undertaken to 'provide an update to the court when the FBI completes the sequestration.'"

Boasberg's filing made headlines on Thursday for showing the Justice Department conceded that there was insufficient evidence to justify the last two of four orders covering the final several months of electronic surveillance of Page during the FBI's counterintelligence investigation of the Trump campaign. The initial order came in October 2016, and the electronic surveillance stretched into the summer of 2017 with a trio of extensions at three-month intervals. It remains unclear whether the Justice Department believes the first two orders targeting Page were similarly flawed.

"Today’s unprecedented court filing represents another step on the road to recovery for America’s deeply damaged judicial system. I hope that this latest admission of guilt for these civil rights abuses by the Justice Department marks continued progress towards restoring justice and remedying these reputationally ruinous injuries," Page said in a statement.

Another brief filing that quietly popped up on the FISA court website Thursday showed the Justice Department requested a deadline extension for the delivery of information regarding minimization procedures designed to stem the disclosure of information about U.S. citizens under surveillance. Boasberg, who seeks the information so that the FISA court can "assess whether the handling and disposition of the information acquired" comports with FISA provisions, wrote that the government's request was granted, and a new deadline has been set for Feb. 5. The original deadline was Jan. 28.

In December, Justice Department Inspector General Michael Horowitz released a report criticizing the DOJ and the FBI for 17 “significant errors and omissions” in its submissions to the FISA court seeking authority to surveil Page and the reliance on British ex-spy Christopher Steele’s salacious and unverified dossier. The watchdog report showed that FBI interviews with Steele's primary source, beginning in January 2017 after the first FISA renewal, "raised significant questions about the reliability of the Steele election reporting."

Following Horowitz's investigation, FBI Director Christopher Wray ordered more than 40 “corrective steps” to address the watchdog's report, including 12 reforms related to the FISA process.

In a Jan. 10 response to the court, Wray said he "deeply regrets" the FBI's failures in the Page FISA process and offered a timetable of reforms and training the bureau is undertaking. David Kris, a former Justice Department lawyer picked to advise the FISA court on the reform process, submitted a brief that pushed for improved communications between FBI and DOJ attorneys on FISA matters beyond what the bureau has proposed.

The FISA court also ordered a review of all FISA filings handled by Kevin Clinesmith, the FBI lawyer who altered a key document about Page in the process to obtain the third warrant renewal. He is now under criminal investigation by U.S. Attorney John Durham, a prosecutor from Connecticut who was tasked by Attorney General William Barr with investigating the origins of the Russia inquiry.
