Federal authorities in Chicago faced a violent clash on Saturday as Border Patrol officers were attacked by individuals who rammed law enforcement vehicles. Secretary of Homeland Security Kristi Noem has vowed to escalate operations, calling the assailants “violent anarchists” and promising reinforcements to restore order.

According to the Department of Homeland Security (DHS), officers were ambushed while on patrol. One of the attackers, Marimar Martinez, was driving a vehicle and armed with a semi-automatic weapon. DHS said she had a history of doxxing federal agents. The woman was shot in defensive fire by CBP officers, treated at Mount Sinai Hospital, and released. Shewas sent to FBI custody. Another driver, Anthony Ian Santos Ruiz, involved in ramming a federal vehicle, was also apprehended.“The scene became increasingly violent as more domestic terrorists gathered and began throwing smoke, gas, rocks, and bottles at DHS law enforcement,” DHS said. Another individual was arrested for assaulting officers at the scene.

President Trump and I have your backs: Kristi Noem

Secretary Kristi Noem posted on X, “Our brave men and women of law enforcement are being targeted and attacked by violent anarchists who seek to tear down America. I want each and every member of law enforcement to know this: President Trump and I have your backs.”In a second post, she added, “Today in Chicago, members of our brave law enforcement were attacked—rammed and boxed in by ten vehicles, including an attacker with a semi-automatic weapon. I am deploying more special operations to control the scene. Reinforcements are on their way. If you see a law enforcement officer today, thank them.”

Trump authorises National Guard deployment

US President Donald Trump responded by authorising 300 National Guard troops to protect federal officers and assets in Chicago. White House spokesperson Abigail Jackson said, “President Trump will not turn a blind eye to the lawlessness plaguing American cities.” The deployment follows weeks of Trump threatening action despite objections from local officials, including Illinois governor JB Pritzker.Pritzker called the deployment unnecessary and “a manufactured performance — not a serious effort to protect public safety.”
