Homeland Security is likely to expand immigration arrests in North Carolina. Here's what to know

It's the latest phase of Republican President Donald Trump 's mass deportation efforts that have sent the military and immigration agents into Democratic-run cities.

Here’s what to know:

Why the Border Patrol is targeting North Carolina

The Department of Homeland Security says it's focusing on the southern state because of so-called sanctuary policies that limit cooperation between local authorities and immigration agents.

Most county jails in North Carolina have long helped federal officials by holding arrested immigrants so agents can take custody of them. But a few jails resisted until a state law effectively made it mandatory last year.

Politics could also be playing a role. The state's mayor is a Democrat and so are the mayors of Charlotte and Raleigh, the state's two biggest cities.

Few details on over 100 people arrested in Charlotte

So far, the U.S. Customs and Border Protection agency says more than 130 people have been arrested in Charlotte.

It says those arrested include people with criminal records. But the agency has offered few other details.

Charlotte has been in the middle of nationwide debates over crime and immigration, most notably after the fatal stabbing this summer of a Ukrainian refugee on a commuter train. While the suspect was from the U.S., the Trump administration repeatedly accused Democrats of backing soft-on-crime policies.

One of the nation's fastest growing regions, Charlotte alone has more than 150,000 foreign-born residents.

Where agents might going next in North Carolina

The mayor of Raleigh says the state’s capital city could see stepped-up immigration enforcement as early as Tuesday.

Mayor Janet Cowell says she doesn’t know how large or how long the operation might be. Immigration authorities haven’t given details. Like the mayor in Charlotte, Cowell says crime is lower in Raleigh this year compared to a year ago.

How North Carolina leaders have responded

Republican leaders say the increased enforcement is needed to restore safety to Charlotte.

But the state’s governor, Democrat Josh Stein, says it's increasing fears and dividing residents. He says Border Patrol agents are picking up random people and targeting them based on their skin color.
