A pre-trial hearing was held Wednesday in the federal perjury and fraud trial of Baltimore City State’s Attorney Marilyn Mosby. The judge presiding over the case granted the government’s motion to bar the defense from claiming Mosby is the target of vindictive prosecution and granted in part the government’s motion to narrow the topics and issues defense experts can testify at trial. The judge ruled in the defense’s favor on whether the jury will hear about prior investigations against Mosby. The trial against Mosby is scheduled to begin on September 19th.
