The Justice Department has ordered federal prosecutors to investigate state or local officials who they believe are interfering with the Trump administration’s crackdown on immigration, saying they could face criminal charges, in an apparent warning to the dozens of so-called sanctuary jurisdictions across America.

"My office is a law enforcement entity. We are going to follow the Constitution and uphold the law," Krasner said as Trump officials threatened consequences for uncooperative local officials.

State and local leaders across the country are bracing for a tidal wave of aggressive immigration policies and possible mass deportations that President Donald Trump has vowed to enact in the hours and days following his inauguration Monday.
