A new report has accused US immigration agencies of failing to root out officers with serious criminal histories, alleging a pattern of domestic violence, sexual abuse, corruption and misconduct among agents tasked with enforcing President Donald Trump's mass deportation drive. The investigation by the Ohio Immigrant Alliance claims at least 25 federal immigration agents or contractors have been criminally charged or credibly accused of offences since Trump returned to office. The group argues the findings expose deep flaws in vetting and oversight at agencies responsible for some of the administration's most high-profile immigration operations. Deadly Shooting Fuels Fresh Scrutiny The report follows last month's fatal shooting of 25-year-old Colombian immigrant David Brouillette by an ICE agent in Maine, a case that has intensified scrutiny of officer conduct. Campaigners say the incident is part of a wider pattern rather than an isolated event. The alliance argues that while the Department of Homeland Security says it is targeting the "worst of the worst" among migrants, some officers carrying out deportation operations have themselves faced allegations of serious criminal behaviour. Cases Raise Questions Over Oversight The investigation began after Cincinnati ICE assistant field office director Samuel Saxon was arrested on assault and strangulation charges involving his partner. Prosecutors later alleged years of abuse, presenting evidence including repeated emergency call-outs, severe injuries and threats of violence. The report also highlights former ICE officer Andrew Golobic, who was sentenced to 12 years in prison after abusing his authority to coerce undocumented women into sex while they were under his supervision. Border Patrol Also Under Spotlight Nearly three-quarters of the cases identified involve Border Patrol personnel, according to the report. It cites current and former agents accused or convicted of offences ranging from child sexual abuse and sexual assault to armed robbery and abuse of detainees. The report also revisits notorious historical cases involving Border Patrol officers, arguing they demonstrate long-running cultural and disciplinary failures within the agency. Leadership Faces Pressure Questions have also been raised over the brief tenure of former Border Patrol chief Michael W. Banks, who resigned in May following media reports citing allegations from former colleagues about his conduct while travelling overseas. Customs and Border Protection thanked Banks for his service and said he helped transform the US border into "the most secure border ever recorded." The agency did not comment on whether his departure was linked to the allegations. Calls for Reform Intensify The Ohio Immigrant Alliance is urging Congress to freeze funding for ICE and Border Patrol until both agencies carry out new workforce screening for domestic violence and extremist links. The Department of Homeland Security rejected suggestions that recruitment standards are inadequate, saying ICE's Office of Professional Responsibility follows established vetting procedures and evaluates all available information before hiring or retaining personnel. The report concludes that many of the alleged offences involved abuse of official authority, arguing that failures to identify warning signs allowed some officers to remain in service despite repeated red flags.
