Gag order

A gag order is an censorship of someone, typically a defendant in a legal proceeding, to prohibit him from speaking publicly against someone connected with the proceeding.

Gag orders are a form of a prior restraint which, in non-judicial contexts, are considered to be presumptively invalid under the First Amendment.

The ACLU told the Obama-appointed judge in the prosecution of Trump in Washington, D.C. that her gag order against Donald Trump was unconstitutional in October 2023, but then she reinstated it anyway. Her ruling is expected to be reversed on appeal.
