NASHVILLE, Tenn. (AP) — Tennessee Gov. Bill Lee has signed a bill that would require law enforcement agencies to communicate with federal immigration authorities if they discover people are in the the country illegally, and would broadly mandate cooperation in the process of identifying, detaining and deporting them.

The Republican signed the measure Thursday, and it takes effect July 1. While the bill’s proponents have argued that Tennessee law enforcement agencies should assist more in immigration enforcement, immigrant advocates have warned that the bill is broad and confusing and could embolden rogue officers to target immigrant families.

“When there is an interaction with law enforcement, it’s important that the appropriate authorities are notified of the status of that individual,” Lee told reporters Thursday. “I think that makes sense. So, I’m in support of that legislation.”
