It was previously known that Trump’s lawyers provided investigators with a file containing 38 uniquely redacted documents, according to court records. However, recently unsealed redactions in the search warrant affidavit indicate that some of those classified files contained “HCS, SI and FISA” flags, according to court filings released Tuesday. These hallmarks indicate that the documents were linked to highly sensitive government programs. “HCS” refers to human sources or spies, often working with the CIA. “SI” refers to intercepts of signals normally handled by the National Security Agency. And “FISA” refers to domestic surveillance and wiretapping related to counterintelligence. These new revelations confirm for the first time that documents related to these sensitive programs were returned to the US government as part of the June subpoena. Previous court filings indicated that when Trump voluntarily returned 15 boxes of materials to the National Archives in January, they contained 184 classified documents, including some with the same HCS, SI and FISA labels, as well as other classification markings. Most of the information in the newly unsealed document has already been made public, but the less redacted version of the affidavit provides some new details about the investigation. The now-vacated redactions in the search warrant affidavit shed new light on the grand jury subpoena federal investigators used to obtain surveillance tapes from Trump’s company that prosecutors used while investigating possible mishandling of classified records at Mar-a – Lago. A federal judge has previously said that subpoena was served on June 24. The newly unredacted filing says the subpoena required the Trump Organization to turn over “any and all video surveillance images, photographs and/or CCTV records from indoor cameras located on the ground floor (basement)” between Jan. 10 and June 24. current year. Trump’s representatives complied with the subpoena on July 6 by giving a hard drive to FBI agents, according to the filing. The Trump Organization is known to have turned over the surveillance footage, but the new filing adds some details about how and when they complied. This story has been updated with additional reports. CNN’s Tierney Sneed contributed to this report.
