President Joe Biden signed an executive order on Monday to address the “crisis of violence” against Native Americans, CNN reported.   

The White House is directing the Department of Justice, Interior Department and Homeland Security “to work with tribal nations,” Biden said at the Tribal Leaders Summit.   

“This builds on the work we did together on reauthorizing the Violence Against Women Act in 2013 when we granted authority to tribes to exercise jurisdiction over non-Indian offenders who commit violence on tribal lands,” he continued.

Interior Secretary Deb Haaland, the nation’s first Native American Cabinet Secretary, joined the president at the signing. Health and Human Services Secretary Xavier Becerra, Attorney General Merrick Garland and Department of Homeland Security Alejandro Mayorkas, as well as first lady Jill Biden, were also in attendance. 

The federal agencies have 240 days to develop a strategy addressing law enforcement issues and “to provide tribal nations with support in implementing tribally centered responses as well,” according to the order.   

CNN reported around 1,500 American Indian and Alaska Native Americans have been reported missing, in the National Crime Information Center. According to the DOJ, Native American women are murdered at a rate over 10 times the national average.   

“A lot of these cases arise in Indian country or involve people who live in Indian country, but they might originate outside of tribal lands, and the patchwork of land holdings and jurisdictions across the country makes it paramount that federal, tribal and local law enforcement agencies coordinate our efforts together,” an official said, according to CNN.
