DOJ and DHS OIGs Release a Joint Review of Law Enforcement Cooperation on the Southwest Border between the Federal Bureau of Investigation and Homeland Security Investigations

Department of Justice (DOJ) Inspector General Michael E. Horowitz and Department Homeland Security (DHS) Inspector General Joseph V. Cuffari announced today the release of a joint review examining law enforcement cooperation on the Southwest border between DOJ’s Federal Bureau of Investigation (FBI) and DHS Immigration and Customs Enforcement’s (ICE) Homeland Security Investigations (HSI). The FBI and HSI share many of the same statutory authorities to investigate certain crimes, underscoring the need for agents to share information and manage investigative overlap effectively.

The Offices of Inspector General (OIGs) found that the majority (63%) of FBI and HSI Southwest border agents did not encounter cooperation failures, and agents reported that task forces improved cooperation and allowed for increased collaboration between the FBI and HSI. However, of the 37% of agents who did experience cooperation failures, 87% reported at least one negative impact as a result, such as loss of trust, unnecessarily prolonged investigations, and failure to gather evidence or apprehend a target.

The report identified several factors that may have contributed to these cooperation failures, including:

  • The FBI and HSI had inconsistent practices, lacked specific policies, and many agents were unaware of requirements related to deconfliction. In February 2019, ICE issued an agency-specific deconfliction policy that may result in improvements.
  • Many agents did not understand the other agency’s mission and authorities and did not trust the other agency or its personnel.
  • DOJ and DHS do not have a memorandum of understanding related to cooperation on the Southwest border.

The DOJ OIG and DHS OIG made five recommendations to the FBI and HSI to address these cooperation challenges. The FBI agreed with all five recommendations. HSI agreed with three of the recommendations and did not concur with two of them.

Today’s report is available:
