Pressure is mounting on tech companies to shield users from unlawful government requests that advocates say are making it harder to reliably share information about Immigration and Customs Enforcement (ICE) online.

Alleging that ICE officers are being doxed or otherwise endangered, Trump officials have spent the last year targeting an unknown number of users and platforms with demands to censor content. Early lawsuits show that platforms have caved, even though experts say they could refuse these demands without a court order.

In a lawsuit filed on Wednesday, the Foundation for Individual Rights and Expression (FIRE) accused Attorney General Pam Bondi and Department of Homeland Security Secretary Kristi Noem of coercing tech companies into removing a wide range of content “to control what the public can see, hear, or say about ICE operations.”

It’s the second lawsuit alleging that Bondi and DHS officials are using regulatory power to pressure private platforms to suppress speech protected by the First Amendment. It follows a complaint from the developer of an app called ICEBlock, which Apple removed from the App Store in October. Officials aren’t rushing to resolve that case—last month, they requested more time to respond—so it may remain unclear until March what defense they plan to offer for the takedown demands.

That leaves community members who monitor ICE in a precarious situation, as critical resources could disappear at the department’s request with no warning.
