A lawsuit has been filed alleging that Immigration and Customs Enforcement agents investigated and threatened a critic based on constitutionally protected speech. The government has responded to the lawsuit, confirming the allegations. The case involves David Streever, who sent an angry email to the then-acting ICE director after a protester was fatally shot. Streever's email was critical of the director, and he was later visited by investigators from the Department of Homeland Security.

The investigators left a note at Streever's house, which is now at the center of the lawsuit. Further details about the case are available from the source. The lawsuit claims that the investigation and warning from ICE were based on Streever's criticism of the ICE director.
