Two days after Alex Pretti was shot and killed by federal officers during an immigration enforcement operation in Minneapolis in January, David Streever was deeply upset. He sent a three-paragraph email criticizing Todd Lyons, who was then the acting director of Immigration and Customs Enforcement (ICE).

Five months later, two federal officers came to Streever's home and gave him a warning, saying his email may have threatened Lyons.

According to CNN, the visit led Streever to file a lawsuit on Monday against several Department of Homeland Security officials. The lawsuit says the officers “went to extraordinary lengths to confront and intimidate him.”

David Streever is a resident of Rochester, New York, who is married and has a 7-year-old daughter. He became one of the first two people to publicly reveal that they received a warning notice from Homeland Security agents over online communications, the other being Paigelynne Gonyea from Syracuse, per NPR.

Streever sent a three-paragraph email to then-acting ICE Director Todd Lyons on January 26, days after Alex Pretti was shot and killed by federal officers during the immigration enforcement surge in Minneapolis.

In the email, titled “What's next,” Streever compared Lyons to a Nazi official and wrote that his conscience would haunt him for justifying the killing of two American citizens in Minneapolis.

Five months later, on June 23, two federal officials showed up at his Rochester home with a written warning notice while he was away on vacation with his daughter.

Streever has now filed a lawsuit against DHS officials, represented by the Foundation for Individual Rights and Expression, arguing his email was protected under the First Amendment.

“Like many Americans, I was deeply upset after the shootings in Minnesota and I felt compelled to do something,” Streever said in a statement, per NPR. “Writing an email to the head of ICE seemed like the least I could do to express my sense of outrage. I never dreamed it would lead to a knock on my door by federal officers or descending on my hotel in the dark of night.”
