The Trump Administration’s crackdown on illegal immigration continues with further pressure on sanctuary cities.

The Daily Signal reports that the Justice Department has confirmed that it will block Byrne Justice Assistance Grants, which account for the lion’s share of federal aid to states and localities for criminal justice, from sanctuary cities, specifically jurisdictions that keep Immigration and Customs Enforcement from talking to local officials and interviewing inmates, or not notifying ICE when they release aliens ICE wants to deport.

It is significant because a large share of the funds awarded in this program go to sanctuary jurisdictions. For example, according to Justice Department records, the four largest grants, and seven out of the top 10 recipients of the Byrne/JAG grants are sanctuaries.

Under the new rules announced by Attorney General Jeff Sessions, these four top grant-getters (New York City; Cook County, Illinois; Los Angeles; and Philadelphia) are likely to be disqualified from these grants in the future if they maintain their current policies toward ICE.

These cities received more than $10 million in grants in 2016.
