A federal judge has temporarily blocked the Department of Homeland Security (DHS) and Immigration and Customs Enforcement (ICE) from using a warning notice against a Rochester resident. The judge cited concerns that the notice, issued after the man sent a harsh email to an ICE official, likely violated his First Amendment rights by chilling his political speech. This ruling highlights the delicate balance between law enforcement’s need to investigate threats and individuals’ right to express themselves, even critically, about government officials.
The case began when David Streever sent an email on June 23, 2026, to then-acting ICE official Todd Lyons. The email contained strong criticism, calling Lyons a “monstrous human being” and comparing him to a historical figure known for his brutality. Following this email, ICE agents attempted to locate Streever at his home, an airport, and a hotel. They eventually left a warning notice for his wife at his residence.
This notice stated, “YOU MAY BE IN VIOLATION OF FEDERAL LAW.” It also warned that receiving the document would be considered if Streever continued alleged criminal activity. Streever subsequently filed a lawsuit, Streever v. Mullin, arguing that ICE’s actions violated his constitutional rights.
First Amendment Concerns
U.S. District Judge Rudolph Contreras issued a preliminary injunction on September 15, 2026, blocking the use of the warning notice. The judge found that Streever likely experienced harm due to the threat of an investigation or prosecution. He concluded that the warning notice probably infringed upon the First Amendment by discouraging Streever’s political speech.
Judge Contreras described the pressure on Streever as a “sword of Damocles,” forcing him to self-censor his views. The injunction prevents DHS and ICE from taking further action based on the warning notice and from issuing similar threats against Streever’s protected expression while the lawsuit is ongoing.
Agency Defense and Court’s Order
Government court filings indicated that the investigation into Streever had closed at the end of June 2026. Federal lawyers defended the practice of in-person investigatory visits accompanied by warnings, calling it a vital tool for investigation and prevention. They argued that such actions do not violate the First Amendment. DHS also stated that ICE investigates all credible threats against its employees and officers, emphasizing that those who threaten law enforcement will face consequences.
However, the court’s order specifically addresses the warning notice and threats directed at Streever’s protected expression during the litigation. It does not negate the government’s stated authority to investigate credible threats. The judge also requested the government to provide the report that closed the investigation into Streever, adding a document-production issue to the constitutional dispute. The injunction remains in effect temporarily, and the case is pending, with both the government’s investigative stance and Streever’s speech claim before the court.
