Investigators said one immigration enforcement official got away with physically assaulting his girlfriend for years. Another admitted he repeatedly sexually abused a woman in his custody. A third is charged with taking bribes to remove detention orders on people targeted for deportation.

At least two dozen U.S. Immigration and Customs Enforcement employees and contractors have been charged with crimes since 2020, and their documented wrongdoing includes patterns of physical and sexual abuse, corruption and other abuses of authority, a review by The Associated Press found.

While most of the cases happened before Congress voted last year to give ICE $75 billion to hire more agents and detain more people, experts say these kinds of crimes could accelerate given the sheer volume of new employees and their empowerment to use aggressive tactics to arrest and deport people.

The Trump administration has emboldened agents by arguing they have “absolute immunity” for their actions on duty and by weakening oversight. One judge recently suggested that ICE was developing a troubling culture of lawlessness, while experts have questioned whether applicants are getting enough vetting and training.

“Once a person is hired, brought on, goes through the training and they are not the right person, it is difficult to get rid of them and there will be a price to be paid later down the road by everyone,” said Gil Kerlikowske, who served as commissioner of U.S. Customs and Border Protection from 2014 to 2017.

Almost every law enforcement agency contends with bad employees and crimes related to domestic violence and substance abuse are long-standing problems in the field. But ICE’s rapid growth and mission to deport millions are unprecedented, and the AP review found that the immense power that officers exercise over vulnerable populations can lead to abuses.

Department of Homeland Security Assistant Secretary Tricia McLaughlin said that wrongdoing was not widespread in the agency, and that ICE “takes allegations of misconduct by its employees extremely seriously.” She said that most new hires had already worked for other law enforcement agencies, and that their backgrounds were thoroughly vetted.

“America can be proud of the professionalism our officers bring to the job day-in and day-out,” she said.

AP’s review examined public records involving cases of ICE employees and contractors who have been arrested since 2020, including at least 17 who have been convicted and six others who are awaiting trial. Nine have been charged in the last year, including an agent cited last month for assaulting a protester near Chicago while off-duty.

Some of the most serious crimes were committed by veteran ICE employees and supervisors rather than rookies.

Among them:

– The assistant ICE field office supervisor in Cincinnati, Samuel Saxon, a 20-year ICE veteran, has been jailed since his arrest in December on charges that he attempted to strangle his girlfriend.

Saxon had abused the woman for years, fracturing her hip and nose and causing internal bleeding, a judge found in a ruling ordering him detained pending trial. “The defendant is a volatile and violent individual,” the judge wrote of Saxon, whose attorneys didn’t return a message seeking comment. ICE said he is considered absent without leave.

– “I’m ICE, boys,” an ICE employment eligibility auditor told police in Minnesota in November when he was arrested in a sting as he went to meet a person he thought was a 17-year-old prostitute. Alexander Back, 41, has pleaded not guilty to attempted enticement of a minor. ICE said Back is on administrative leave while the agency investigates.

– After an ICE officer in Florida was stopped for driving drunk with his two children in the car in August, he tried to get out of charges by pointing to his law enforcement and military service. When that failed, he demanded to know whether one of the deputies arresting him was Haitian and threatened to check the man’s immigration status, body camera video shows.

“I’ll run him once I get out of here and if he’s not legit, ooh, he’s taking a ride back to Haiti,” Scott Deiseroth warned during the arrest.
