US prosecutors have recommended that the Department of Justice (DoJ) brings criminal charges against Boeing.

Boeing declined to comment when contacted by the BBC but previously it has denied violating the deferred prosecution agreement.

The recommendation is not a final decision and the details of any potential criminal action are not known, according to CBS, the BBC’s US partner.
