Judge Amy Berman Jackson of the US District Court for the District of Columbia issued a gag order on Friday prohibiting Roger Stone, attorneys on both sides, and all witnesses and interested parties from making statements to the media or the public regarding Stone’s criminal case.

All listed persons are further prohibited from making any statements to the media “when they are entering or exiting the courthouse, or [while] they are within the immediate vicinity of the courthouse.”

The court considers such statements “substantially likely to have a materially prejudicial effect,” in “widely publicized or sensational criminal case[s].” The purpose of the order is to “seat a jury that has not been tainted by pretrial publicity.” The court also cautioned Stone, noting that “one factor that will be considered in the evaluation of any future request for relief based on pretrial publicity will be the extent to which the publicity was engendered by the defendant himself.”

The order comes following a separate civil complaint form Jerome Corsi filed last week, coupled with an amici curiae brief filed in the criminal case alleging defamation of Corsi by Stone.

Corsi is an American political commentator who is known for popularizing the rumor that Barack Obama was not born in the US. Some news outlets are alleging that Corsi may be the infamous “Person 1” referenced in Mueller’s complaint.
