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.

President Donald Trump's administration has directed federal prosecutors to criminally investigate state and local officials who attempt to resist its immigration enforcement efforts, according to a memo to Justice Department staff seen by Reuters.

The directives to Justice Department employees could face fierce blowback from legal advocacy groups and officials in cities and states led by Democrats.

President Donald Trump's administration has directed U.S. prosecutors to criminally probe state and local officials who resist immigration enforcement efforts, intensifying a sweeping crackdown that Trump launched the day he took office.

The Justice Department's new leadership directed prosecutors to potentially charge state or local officials who impede President Trump's immigration policies.

The Trump administration is directing the Justice Department to dramatically boost its efforts on immigration enforcement, making it an agency top priority.

Acting Deputy Attorney General Emil Bove said that local laws that don't match Trump's immigration plans threaten national security.
