United States Park Police and ICE: Traffic Stops on D.C. Parkways Lead to Immigration Arrests Without Warrants

A breaking investigative report published Monday, March 16, 2026, exposes how United States Park Police traffic stops on Washington D.C. area parkways have become a pipeline for ICE immigration arrests — in at least ten documented cases, without a warrant or probable cause. Court records filed in a class-action lawsuit against the Department of Homeland Security are pulling back the curtain on a federal enforcement operation that critics say blurs the line between traffic safety and immigration policing.

United States Park Police and ICE: Ten Documented Arrests Revealed in Court Records

A review of filings in a class-action lawsuit against the Department of Homeland Security identified at least ten arrests of immigrants by ICE in operations that involved United States Park Police in the D.C. area. The review was conducted by Capital News Service and the Howard Center for Investigative Journalism at the University of Maryland and covered court records filed between September 2025 and February 2026. The lawsuit alleges DHS violated federal law by making immigration arrests in Washington without a warrant or probable cause.

At least three of the documented arrests targeted workers traveling in commercial vehicles. Many declarations in the lawsuit were filed under pseudonyms, with plaintiffs citing fears of retaliation against themselves or their families. Advocates say the court documents capture only a fraction of the immigration arrests occurring on United States Park Police-patrolled roads and parkways.

How a Routine United States Park Police Traffic Stop Becomes an ICE Arrest

United States Park Police tailed a man while he commuted home from work. When he stopped to get some water, ICE showed up and took him away. A pool maintenance worker was stopped by United States Park Police, but it was ICE agents who scanned his driver's license and arrested him on the spot.

ICE scanned his license, arresting him immediately, then snapped the document in two, telling him he had no right to be in the country — despite his having no criminal record, no outstanding ICE warrant, and having lived in the United States for 13 years. A third December arrest targeted a mechanical repair worker from Nicaragua who was present in the country on humanitarian parole and was dispatched to a detention center for deportation.

Trump Executive Order Established the D.C. Safe and Beautiful Task Force

In March 2025, President Donald Trump announced the D.C. Safe and Beautiful Task Force through an executive order. Led by Stephen Miller, the president's Homeland Security Advisor, the task force facilitates collaboration between a range of federal agencies, including DHS and the Department of the Interior, which oversees United States Park Police. The order tasked the group with increasing police presence in the city and strictly enforcing public safety and immigration laws.

Back in December, the task force organized the traffic stop where the pool maintenance technician was arrested. On that day, agents from ICE, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and the Diplomatic Security Service all reported to a local parkway to assist United States Park Police, according to an ICE arrest record filed in the lawsuit against DHS.

United States Park Police Denies Immigration Enforcement Role

United States Park Police insists it plays no immigration enforcement role, maintaining that all stops are made on traffic and public safety grounds. A spokesperson pointed to a longstanding ban on commercial vehicles using certain parkways — citing low-clearance bridges and narrower lanes — and said violations typically draw a citation. "After we have completed the reason for our stop, DHS, if present, may have follow-up questions that may result in an arrest," the spokesperson said.

The central question raised by the lawsuit and the court record review is where, in day-to-day enforcement, traffic safety ends and immigration enforcement begins.

United States Park Police Expansion: 300 New Officers and $70,000 Signing Bonus

United States Park Police is set to expand its D.C. roster by more than 300 officers by spring and is currently advertising a $70,000 signing bonus for recruits on its website.

Senate Democrats have raised serious alarms over the expansion. Senator Jeff Merkley of Oregon led a group of senators including Dick Durbin, Ron Wyden, and Chris Van Hollen in a letter demanding the Trump administration suspend its plans, warning that the National Park Service is in the process of doubling the number of United States Park Police officers in Washington D.C. with the stated goal of transforming the force into a federal police force deployed across the entire city, rather than following its traditional mission of safeguarding national monuments.

White House Defends United States Park Police and ICE Joint Operations

The White House defended the joint enforcement arrangement. "President Trump has transformed DC from a crime-ridden mess into a beautiful, clean, safe city," said White House spokesperson Taylor Rogers. The administration did not directly address the specific arrests described in the court records or answer questions about whether warrants were obtained prior to any of the ten documented immigration arrests.

United States Park Police operations currently cover the National Mall, the C&O Canal towpath, the George Washington Memorial Parkway in Virginia, the Clara Barton Parkway in Maryland, and the federally maintained segment of the Baltimore-Washington Parkway in Maryland — all of which have become active corridors for the joint enforcement operations described in the lawsuit.
