On February 8, 2023, while arguing on behalf of fired NYC workers who declined covid vaccination, attorney John Bursch stated in open court that unvaccinated teachers in New York City were flagged with problem codes in their personnel files, and when that occurred "their fingerprints are sent with that flag to the FBI and the New York Criminal Justice Services."

You can listen to Bursch make this statement at the 5:30 mark of the audio recording of the court proceeding.

The source of this information is Betsy Combier who wrote an affidavit (see pdf below) in the Kane v. de Blasio case where she stated unvaccinated teachers were given a "problem code" label that was "then sent to the national databases at both the Federal Bureau of Investigation" (FBI) and the Department of Justice (DOJ).
