Documents obtained by The Associated Press show that federal border agents are pulling out of a Louisiana immigration crackdown and heading to Minneapolis. The shift appeared to signal a wind down of the Louisiana deployment that began in December and had been expected to last into February.

Ahead of the anniversary of the rampage, officials are ramping up security measures. Some 350 National Guard members arrived Tuesday.

Records reviewed by The Associated Press show the state's fusion center is tracking message boards for threats to agents and compiling updates on public sentiment.

President Donald Trump says National Guard troops will be deployed to New Orleans, an announcement coming on the eve of a planned federal immigration crackdown in and around the city.

Federal agents are set to conduct a two-month immigration crackdown starting Dec. 1. The operation aims to arrest around 5,000 people across southeast Louisiana and Mississippi.
