A Texan is accused of making terroristic threats to the nation’s Homeland Security secretary and federal law enforcement officers.

Robert King was arrested in McKinney, Texas, after authorities said he would “open fire” on U.S. Immigration and Customs Enforcement agents and at Department of Homeland Security Secretary Kristi Noem.

King reportedly made the threat on social media indicating he would “open fire” if agents were seen in his neighborhood.

Homeland Security Investigations announced the arrest of King on Wednesday, calling his post “alarming.” Authorities said King is a U.S. citizen.

Local media said a DHS spokesperson reported to them that King’s social media post characterized Noem as a Nazi.

The threats come amid ongoing tensions surrounding the Trump administration’s stance on illegal immigration, which has fueled public outcry and, in some cases, calls for violence against federal law enforcement. In response to such threats, Noem posted a statement on Sunday warning that any attempt to harm law enforcement would be met with swift legal action.

“If you threaten or attempt to harm a law enforcement officer we will find you and prosecute you to the fullest extent of the law,” she wrote.

As the debate over immigration policy continues, some social media users have openly incited violence against ICE agents. One TikTok user posted a video urging others to “shoot on sight” if ICE agents attempt to arrest individuals or their loved ones.
