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 led to federal officers visiting his home.

The email was sent in response to an incident involving an immigration officer. The plaintiff's attorneys say the email was deemed a threat, prompting the visit from officers. The plaintiff was not at home at the time, as he was traveling abroad.

Further details about the lawsuit and the events leading up to it are available from the source. The lawsuit was filed in Washington D.C. and alleges that the agency's actions were unjustified.
