A member of the FAA’s internal investigations department notified the FBI a day after the siege that Strong had been at the Capitol, the affidavit said.
Strong faces three charges: violent entry and disorderly conduct on Capitol grounds, entering or remaining in a restricted area, and being disorderly or disruptive in a restricted area.
Strong works for the FAA in San Bernardino, and the FBI began investigating him on Dec. 30, a week before a violent mob stormed the Capitol.
The investigation began after someone told the agency that Strong “had been showing signs of behavioral changes over the last few months including stockpiling items and telling others to get ready for marshal law, rioting, and protesting,” the FBI affidavit said.
The FBI was told that Strong had claimed World War III was going to occur on Jan. 6 and that the extremist group QAnon would cover the debt for a new truck he recently had purchased.
