At least six states have authorized National Guard troops to assist U.S. Immigration and Customs Enforcement (ICE) in administrative and logistical roles.

An Immigration and Customs Enforcement memo said that National Guard troops would assist in the deportation process for migrants in their custody.

President Donald Trump announced Monday that he was placing the D.C. police under direct federal control and will deploy the National Guard to the streets of Washington to fight crime, an extraordinary flex of federal power that stripped city leadership of its ability to make law enforcement decisions and could expose residents of the nation’s capital to unpredictable encounters with a domestically deployed military force.
