The DOJ filed a new lawsuit against New York City, accusing it's leaders of blocking immigration enforcement with sanctuary city policies.

The suit cites a number of provisions of New York City code and other policies, including a 2011 provision that bars the Department of Correction from honoring civil immigration detainers from U.S. Immigration and Customs Enforcement and rules governing the NYPD that limit police officers' ability to cooperate with federal immigration authorities.

The action comes days after an off-duty Customs and Border Protection officer was shot in the face during an ambush robbery attempt.
