A surge of federal agents arrived in Charlotte, North Carolina Saturday to take part in immigration arrests despite protests from the mayor and other local officials.

Customs and Border Patrol Commander-at-large Greg Bovino and his team are eyeing Charlotte and New Orleans as the next cities for increased immigration enforcement, according to multiple sources. The plans are preliminary and could change, the sources told ABC News. It is unclear if they would run at the same time or one city would go first.
