NEW YORK, Aug. 13, 2018 — Donald Trump today acknowledged the existence of nondisclosure agreements for White House staff. Brian Hauss, staff attorney with the American Civil Liberties Union’s Speech, Privacy, and Technology Project, issued the following statement in response:
Donald Trump cannot muzzle federal employees. The First Amendment protects federal employees’ right to speak in a private capacity about matters of public concern. If such NDAs prohibit employees from revealing all information they learn of at work, without consideration of what the information is, they are unconstitutional and unenforceable.
