As reported by Reuters ( here ) some state and local courts in the United States permit cameras and allow live TV broadcasts of certain proceedings, but federal courts largely do not. Broadcasting and photographing criminal proceedings in federal courts is prohibited under the Federal Rule of Criminal Procedure (see here ). A few federal district courts and circuit courts allow recordings “under certain, limited circumstances,” according to a 2019 report by the Congressional Research Service (see page 10, here). In Wisconsin, television cameras and still photographers are allowed in any courtroom proceeding, as stated in Chapter of its Supreme Court rules ( here ), which were adopted in 1979.
