A lawsuit has been filed against U.S. Immigration and Customs Enforcement. The plaintiff, a U.S. citizen, claims his First Amendment rights were violated. He had sent an email to the agency's former head, which was deemed a threat.

The email was sent in response to a fatal shooting during an anti-ICE demonstration. The plaintiff's attorneys say he was not at home when federal officers arrived with a warning notice. His wife was presented with the notice instead.

Further details about the lawsuit and the circumstances surrounding it are available from the source, KSAT 12. The lawsuit was filed in Washington D.C. and alleges that the agency overstepped its bounds in responding to the plaintiff's email.
