Before the new program, the systems were available to federal, state and local law enforcement, but not to all tribes.

Tulalip Chairman Melvin Sheldon Jr. said TAP will empower tribal law enforcement agencies nationwide by giving them the tools they have sought for years to protect their communities. In addition to using the database during firearms purchases, it's used for background checks when placing children with a foster parent.

Deputy Attorney General Sally Yates said the "landmark effort" strengthens both the sovereignty and safety of American and Alaska Native people.

"Since its launch in 2015, this project has not only helped law enforcement locate suspects, rescue victims and extradite captured fugitives, but it's also made it easier for civil courts to enter and enforce orders of protection for domestic violence victims," Yates said in a statement.

During 2016, the tribes received a kiosk workstation that gave them access to national systems.

The tribes used the program for variety of criminal agencies, including law enforcement, criminal courts and jails. It lets tribes enter arrests and convictions into national databases.
