Federal agents have issued a second warning to a New York resident over online comments criticizing U.S. Immigration and Customs Enforcement, fueling fresh claims from free speech advocates that the Trump administration is targeting protected political speech.David Streever, of Rochester, says federal officers visited his home while he was traveling in Finland last week and left a warning notice with his wife, alleging an email he sent months earlier to ICE leadership constituted a threat.According to his attorney, Adam Steinbaugh of the Foundation for Individual Rights and Expression, the warning stemmed from a January email sent to then-acting ICE Director Todd Lyons after ICE officer Jonathan Ross fatally shot Minneapolis resident Renee Good during an anti-ICE protest.This photo provided by David Streever shows federal officers at David Streever's home in Rochester, N.Y. in June 2026In the email, Streever called Lyons "a monstrous human being" and wrote that he "will never know peace." He also predicted that Lyons' handling of the shooting "will lead to your downfall" and that he would become "a sad, despised man who eats himself alive with shame."Steinbaugh said federal agents later attempted to meet Streever at a New York City hotel after he returned from Finland, but hotel staff turned them away.ICE declined to discuss the case, citing an ongoing investigation.In this image from video provided by Sheilia Milledge, Paigelynne Gonyea, right, is presented with a form at a polling place on Tuesday, June 23, 2026, in SyracuseIn a statement, the agency said it investigates "all credible threats" against its employees and leadership, including the ICE director.Streever's legal team insists that the email is protected by the First Amendment and does not constitute a criminal threat."A true threat is a serious expression of an intent to commit violence. This email doesn't even come close," Steinbaugh said. "It's political speech. It's an act of petitioning your government."David Streever of Rochester pictured with his daughterStreever said he was shocked by the federal response."Like many Americans, I was deeply upset after the shootings in Minnesota," he said. "Writing a letter 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."The case surfaced just days after another upstate New York resident, Syracuse poll worker Paigelynne Gonyea, said federal officers approached her at a polling place during New York's primary election over social media posts about the same fatal shooting.This photo provided by Paigelynne Gonyea shows a form she says she received from ICE officialsGonyea said officers questioned her over a January post featuring a photograph of Ross in which she wrote: "I think today is a great day for Jonathan to be indicted."The Department of Homeland Security has disputed that account, saying the investigation centered on a different post that allegedly shared the officer's home address. A department spokesperson accused Gonyea of committing a federal crime by "doxxing" a law enforcement officer and warned that such conduct would be investigated.The New York Attorney General's Office said it is aware of both incidents and is reviewing the interaction involving Gonyea at the polling location.Civil liberties groups argue the two cases raise serious concerns about government intimidation.Nathan Freed Wessler, deputy director of the ACLU's Speech, Privacy and Technology Project, said Americans have a constitutional right to criticize public officials and warned that visits from federal agents over political speech could have a chilling effect."No one should be tracked down at their home or hotel room by federal agents in retaliation for expressing opposition to the government's actions," Wessler said, calling it "an abuse of power" if protected speech is being targeted.Federal authorities have not announced criminal charges against either Streever or Gonyea.
