President Donald Trump wants to crack down on so-called sanctuary cities by stripping federal grant money from localities that harbor unauthorized immigrants. The plan is one of the executive orders Trump has signed in his first days in office.

What is a sanctuary city? 

There is no single definition, rather it is a broad term applied to jurisdictions that have policies aimed at limiting cooperation with federal immigration enforcement actions.

Some jails, for example, refuse to prolong the detention of people who are about to be released after completing their sentences for federal authorities seeking to deport them.

Cities, counties and some states have adopted "sanctuary" policies.

Many of the largest cities in the country – such as New York, Chicago and Los Angeles - have forms of such policies.

What about Georgia? 

Georgia has outlawed sanctuary cities in the state since 2009.

State lawmakers last year went a step further, in response to the killing of a California woman by a man who was in the country illegally.

The new Georgia law requires local governments to certify they're cooperating with federal immigration officials in order to get state funding.

Atlanta has said that it remains a welcoming city for immigrants, but stops short of labeling itself a sanctuary city.

What’s next? 

College campuses appear to be the next battleground. Nationally, there has been a movement to declare some universities “sanctuary campuses” to shield those students studying in the United States without legal status.

Among Georgia's public universities, the issue appears to be a non-starter. Georgia's Board of Regents said in December that while they respect the rights of students, faculty and staff to express their views, "calls for institutions to implement policies and procedures that may violate state and federal laws are unacceptable."

The incoming president of Emory University – a private school – said it would not be a "sanctuary campus."
