How does the FBI interact with other federal law enforcement agencies?

To do its job, the FBI works with both government and private sector partners every day and at every level—local, state, federal, tribal, and international. In some cases, these partnerships directly support our investigations and operations. In other cases, they enable mutually beneficial information sharing that help us to better understand emerging threats and foster crime prevention initiatives.

The FBI has long believed that cooperation is the backbone of effective law enforcement. The FBI routinely cooperates and works closely with all federal law enforcement agencies on joint investigations and through formal task forces—both national and local—that address broad crime problems and national security threats. 

The FBI's Office of Partner Engagement builds bridges, creates new partnerships, and strengthens and supports existing relationships between the FBI and others within the law enforcement community.
